It's time for computer designers to think outside the box. From Microsoft Corp. to Silicon Valley start-ups, technology companies are introducing computers with fundamentally new forms.

At a technology conference sponsored by The Wall Street Journal, Microsoft today unveiled the fruits of six years of research pushed by Chairman Bill Gates -- a computer designed like a table with a touch-screen. The system, called Surface and aimed initially for use in hotels and casinos, includes features that allow users to buy tickets to events, wirelessly retrieve and display photos and play games. It goes on sale later this year.

At the same event today, an Oakland, Calif., start-up called Livescribe Inc. will introduce a pen-shaped computer that can make audio recordings and link them to written notes.

And Palm Inc. co-founder Jeff Hawkins, who helped lead the design of the Silicon Valley company's pocket computers and Treo smartphone, plans to disclose what Palm calls a "new category" of mobile device. Though few details are known, one industry executive expects the gadget to be somewhat larger than Palm's existing products and to include wireless networking.

The new products, to be shown at the "D: All Things Digital" conference in Carlsbad, Calif., are just a few examples of the quest by large and small technology companies to change the shape of computers. After an initial innovation boom, most PC makers for years have churned out cookie-cutter desktops and laptops. Though they have on the whole become less expensive and smaller, other major changes have been rare.

But the picture is changing, inspired by innovations such as Apple Computer Inc.'s iPod and other stylish products. Besides working on esthetics, companies are experimenting with new uses for computers and new ways for people to interact with them -- including wider use of voice input, styluses and touch-screens. Hewlett-Packard Co., for instance, sells a PC called TouchSmart, at $1,800, that is designed for a kitchen counter and tasks such as looking up a recipe or a phone number without using a keyboard.

"The PC is running away as fast as it can from what it used to be," says Mark Rolston, a senior vice president at frog design inc., a consultancy that has helped Hewlett-Packard and other companies develop hardware and software designs.

Which new variations will catch on widely remains to be seen. Many of the new items require big changes in the way people use computers, and are often pricey. At the same time, their success depends on a critical mass of software companies building applications that consumers find useful.

One reason PC makers haven't taken more creative risks in the past is the narrow profit margins in the fiercely competitive business, which leave manufacturers little money to spend on product design. Microsoft and Intel Corp. -- which have healthier profit margins from their near-exclusive positions in PC operating systems and microprocessors, respectively -- have been among the leaders in trying to spur new uses and designs for PCs.

Intel, as part of a branding effort called Viiv, this spring held a contest to encourage innovative designs by companies that make the living-room PCs that allow TVs to play digital movies and other Internet content. Trigem Computer Inc., a South Korean company, won a $700,000 first prize for a stylish system called the Black Crystal that looks like a piece of high-end stereo equipment. NS Optimum Ltd., a British company, developed a PC called Argon that looks like a metallic skull with glowing red eyes. Both Trigem Computer and NS Optimum are expected to sell the items, but have not disclosed the timing or pricing.

Genevieve Bell, an Intel senior researcher and anthropologist who studies how different cultures view technology, says many designers haven't caught up to the way PCs are increasingly used for entertainment and networking. "People are inherently quite social," she says. "The challenge is, how do we make designs that echo that."

Building a computer into a table that several users can gather around is one way that researchers are tackling that challenge. Hewlett-Packard, for example, is using the approach in a research prototype called Misto.

For Mr. Gates, Surface is part of a quest to expand the definition of the PC. "I've been saying the last few years that the thing people are underestimating the most is how 'natural interface' will change computing," he said in an interview. For many years, he has promoted speech input, stylus-based computing and, with Surface, visual recognition.

So far, those variations on the keyboard have been slow to catch on. Microsoft five years ago introduced the Tablet PC, which features a large screen that can be controlled with a stylus rather than a keyboard. While some companies use them as portable computers, they still haven't caught on widely.

Surface, a table with a square acrylic top measuring 30 inches on the diagonal, combines five cameras with Wi-Fi and Bluetooth wireless networking to detect objects and movement. It uses a version of the Windows Vista operating system with additional Microsoft software. As users move their hands on the table top, cameras help translate the motions into commands. For instance, users can select a color by touching a virtual palette and then "paint" images on the screen with fingers or a brush.

Wireless technology transfers stored photos from a digital camera or cellphone placed on the table to the Surface screen. A motion of the hand on the touch-screen can make the images larger or smaller. They can be moved to another camera or a hard drive by sliding the images across the table -- much as one would slide a picture across a regular table.

In a recent demonstration, Microsoft executives showed how the object-recognition feature could work for Harrah's Entertainment Inc. Placing a loyalty card for the casino operator on the table summons a map of Caesar's Palace. Tapping on the casino's different venues reveals show times, menus, descriptions of nightclubs and other information, allowing a guest to book tickets, make reservations or even gamble. The executives see new ways for establishments to interact with customers. Placing a wine glass with a tag similar to a bar code on the table, for example, could call up details about the wine and its vineyard.

Harrah's, Starwood Hotels & Resorts Worldwide Inc. and T-Mobile USA Inc., a unit of Deutsche Telekom AG, expect to use the system, the companies say. (T-mobile would use it at its stores to give customers information on new products and services.) International Game Technology, a distributor of gaming machines, will distribute Surface. Starting at $5,000 to $10,000, and needing considerable customization, Surface isn't suited for individual consumers now. But Microsoft expects high-profile hotel and restaurant operators to bring exposure.
From the D Conference in Carlsbad, Calif., Microsoft CEO Steve Ballmer tells WSJ's Rob Guth that it's important for the health and growth of company to be both an enterprise and consumer entity. (May 30)

"Literally millions of people will see it through the different partners we have," Mr. Gates says. "But the big numbers come when our hardware partners pick it up and build devices for the office and home environments." Mr. Gates expects that in three to five years greater sales volumes will help drive down the cost of the Surface technology, enabling the company to "get to price points that are under a thousand dollars for broad usage," he says.

Livescribe's pen-shaped computer, meanwhile, is initially aimed at college students. It builds on technology that was invented by Sweden's Anoto Group AB and used in the popular Fly Pentop Computer from LeapFrog Enterprises Inc.

Livescribe's founder and chief executive, Jim Marggraff, previously worked at LeapFrog and for Anoto. The approach relies on special paper with tiny dots that help a sensor in the pen distinguish locations on a page, and assign them special functions. With The Fly, for example, users can draw a calculator and then touch the numbers to trigger a calculation heard through a speaker or ear phones.

Livescribe's "Smartpen" adds a microphone and a small display on the side of the pen. A user can tap on a section of written notes, for example, and call up a recording in the pen of what an instructor was saying when those words were written. Mr. Marggraff, who expects to deliver the device in October for less than $200, plans to create a community of programmers to write exchange applications for the Smartpen. "I believe this will affect the way people think," he says.

Storage Strategies

Need more room for your files?
Here are your options.By JESSICA E. VASCELLAROMay 14, 2007 WSJ:
********************
Computer users' hard drives are bursting at the seams thanks to the floods of digital photos, videos and music they regularly consume. Now, numerous new products and services are trying to help manage the deluge.
Older storage strategies such as transferring files to discs are giving way to potentially time-saving solutions like external hard drives with pipelines into online storage accounts and home-network hubs that store and share files for multiple computers.THE JOURNAL REPORT [See the full report]1As businesses rely more on mobile devices2, wireless companies are improving their coverage -- building by building. Plus, for a century, architects have speculated3 about the house of tomorrow. Where did they go wrong?• See the complete Technology report4.
Online-only services that enable users to upload their files to the Web and store them there are also growing more popular, despite often painfully slow upload speeds and concerns about data privacy and security.
Enterprises and small businesses have been adopting these more complicated storage methods for years. But now they are gaining more traction among consumers as new technologies drive prices down and households' needs for personal-data storage become more pressing.
A technology-savvy consumer can easily require an additional 20 or 30 gigabytes of space to house their digital content. One gigabyte holds around 250 songs; about half of a two-hour movie; or around 1,000 photos, although it varies depending on their resolution.
Here is a look at various personal data storage options and what to expect when you try them:
EXTERNAL HARD DRIVES: Driven by strong consumer demand, sales of external hard drives are skyrocketing. U.S. retail sales of external drives, which plug directly into a computer for extra capacity often in the range of 100 gigabytes or more, rose 73% from 2005 to 2006, according to NPD Group. "External storage remains far and away the simplest, easiest and most understandable method for the vast majority of consumers," says Stephen Baker, an analyst at NPD Group.
Manufacturers are trying to differentiate their products by selling drives that are more compact and stylish and that integrate with increasingly popular Internet storage services. Last month, for example, Fabrik Inc. launched a new line of SimpleTech drives designed by Pininfarina SpA, an Italian company that helps design Ferrari sports cars. The devices, which start at $99 for 160 gigabytes of space, come bundled with two gigabytes of free online storage through Fabrik's Internet data-storage service, MyFabrik.com5. The product allows users to upload files to an online account, where they can share data with friends and create slide shows. Fabrik, of San Mateo, Calif., purchased the consumer-product business of SimpleTech Inc. in February.
Seagate Technology Inc.'s new FreeAgent Go, which starts at around $100 for 80 gigabytes of space, comes in an espresso color with a glowing amber strip. In addition to storing files, the lightweight device can carry passwords, contacts and settings between machines as well. FreeAgent Pro, a more robust device that starts at around $150 for 320 gigabytes, sits on the desktop but comes with an additional 500 megabytes of storage through Seagate's online-storage service.
Jon van Bronkhorst, executive director of product-line management for Seagate, says the new products are designed to help consumers access their files in multiple places without compromising the reliability and fast speeds of using an external drive. "It is about giving consumers the flexibility to use their stuff whenever and wherever they want to," he says.
ONLINE STORAGE: Plummeting bandwidth costs and higher broadband penetration are inspiring a flurry of new online-storage offerings that tout the convenience of being able to access stored data from any Internet-connected computer.
Penetration of the services is still relatively low in part because consumers are wary of trusting their data to a third party that may go out of business. Only 9% of U.S. Internet users say they have used an online-storage service, according to research firm Parks Associates, compared with 51% who say they back up their files with CDs or DVDs.
New products and services are trying to win new business through lower prices and additional features like integration with Internet software applications.
Sites like Omnidrive Inc., based in Menlo Park, Calif., Box.net, Palo Alto, Calif., and Xdrive, a unit of Time Warner Inc.'s AOL, often offer as much as a few gigabytes of storage free and charge several dollars a month for additional capacity. Others, like ElephantDrive Inc., Los Angeles, focus on backing up files, offering one gigabyte of space free and $9.95 a month for unlimited backup.
The services often let users upload files either through a software client or through their browsers. Or users can preselect certain files they want backed up automatically, in which case the program will save copies of the files online at regular intervals.
Alex Iskold of Livingston, N.J., uses ElephantDrive.com6 to back up 10 gigabytes of music, hundreds of photos, and documents for work like PowerPoint presentations. "It is really powerful to have things stored online," says Mr. Iskold, the 34-year-old chief executive of AdaptiveBlue, a Web-personalization start-up.[image]
But other users complain that such services, even on a broadband Internet connection, are slow, taking hours to upload hundreds of pictures. And some users complain that their files aren't always available. For example, Larry Medina, 51, of Danville, Calif., recently stopped storing photos on Mozy.com7, from Berkeley Data Systems Inc. of American Fork, Utah. After twice being unable to access the pictures (he says after logging in he received a message that the service was waiting for a response), he decided to store backups of them in a remote location on DVDs instead.
Josh Coates, chief executive of Berkeley, says the errors were likely "glitches" related to back-end software upgrades.
NETWORK STORAGE: Consumers now also have the option of replicating the convenience of an online storage service on their own home network. The solutions, offered by companies like Cisco Systems Inc. and Hewlett-Packard Co., enable a user to store files on a separate home-network device that can be accessed from multiple computers in the house.
Mike Sweeney of Orange, Calif., recently set up a $250 SimpleTech network-storage device in order to more easily share files, photos and documents across some half a dozen home computers. To date, he has stored some 200 gigabytes of files on the device for easy access and safekeeping. "It is very cheap insurance," says Mr. Sweeney, a 46-year-old network-security administrator.
But setting up such services can require a substantial investment of dollars and time. Such devices can range in price from a few hundred to nearly a thousand dollars, depending on the capacity of the device and whether the user is building a home network from scratch. In the latter case, the setup can be trying. The user must first link the computers through a network router -- basically a central switchboard -- and then plug the storage device into the network router as well. Once the computers in the network recognize the Internet address of the attached storage device (which may require the user to disable certain firewalls), it acts as a separate standalone drive, to which the user can drag and drop files.
To entice consumers to make the investment, storage companies are rolling out products that are smaller and cheaper, and adding features such as the ability to stream multimedia from the Internet to the home network without hogging space on their computers.
Linksys, a division of Cisco, plans this summer to launch a network appliance and storage device that can store more than a terabyte of data on two hard drives, and stream data from the storage device to a digital television or stereo. The base price of the device is $179.99. The hard drives are sold separately.
H-P's Media Vault similarly acts as a bridge between various home computers that have installed the Media Vault software. The device costs $349 for 320 gigabytes of storage or $499 for 500 gigabytes.

Tape backup continues its role in long-term storage.

Tape backups have proven to be remarkably resilient as a storage technology. According to research from the Enterprise Strategy Group (ESG), less than a third of the respondents backed up to tape only, less than one quarter backed up to disk only and about 50% used a mix of disk and tape. "We've all known that tape backup isn't our best solution," says Heidi Biggar, analyst at ESG in Milford, Mass. "But as users bring disk into their environment, they're not throwing away their tape investment." Consequently, storage professionals must understand tape technology and its role in the enterprise. This article highlights the basics of tape backup, outlines the main implementation considerations, explores the experiences of several real users and looks ahead to the future of this long-standing storage technology.
Understanding tape backup technology
Magnetic tape remains a quintessential storage technology. Early on, a long strip of thin plastic coated with magnetic recording media was simply spooled onto reels. Later, the reels were packaged into cassettes or cartridges to ease loading/unloading, simplify storage, protect the media from accidental damage and improve reliability by blocking dust. Once a cartridge is inserted into a tape drive mechanism, the media is passed at a constant speed across a stationary read/write head. These basic principles have gone virtually unchanged in over 50 years. As time went on, tape drives diversified into unique architectures, such as Travan, DDS, DLT and more recently, LTO. These tape backup architectures are not interchangeable, so tape systems must be selected for their technological longevity and media costs. You can learn more details about tape technology in our All-In-One Backup Research Guide.
Tape backup technology proved appealing for several reasons. The cost per gigabyte is still very low compared to disk. An LTO-3 cartridge with 400 GB of native capacity costs less than $100 (about 25 cents per gigabyte) -- half that with 2 to 1 compression enabled. Tape backup also offers "endless" storage capacity. Where a disk storage system has a fixed maximum capacity, tape storage can be expanded simply by using more cartridges. "You can see the leverage you'd get with 10 cartridges [in a single tape drive] versus 10 disk drives," says Robert Abraham, analyst at Freeman Reports in Ojai, Calif. Further, tape offers a "write once" nature that is ideal for long-term archival storage.
However, tape backup suffers from some disadvantages that have been exacerbated by the ready availability of disk systems. The principle problem is performance. Even the 160 megabytes per second (MBps) compressed transfer rates in LTO-3 tapes pale in comparison to disk systems. "The [tape] access times are very slow -- 1,000 times slower," Abraham says, noting that it's much more difficult and costly to retrieve data from tape. This wasn't such an issue years ago, but with corporate data volumes increasing from 50% to 100% each year, tape backup windows and recovery time objectives (RTO) have simply become prohibitive for many organisations, especially businesses that need to operate 24/7. The cost of disk is still seen as an advantage for tape, but disk costs are falling quickly and technologies, like data deduplication, are dramatically improving disk efficiency, allowing data to remain on disk for longer than ever before. (See Data deduplication explained for more details and user studies on deduplication technology.)
Today's tape backup technology and performance
While tape technology has changed very little, storage and recovery needs have evolved dramatically -- yet users are reluctant to discard their existing tape backup systems. This has changed the role of tape from a primary backup vehicle to long-term disaster protection. "Tape is [now] the doomsday tier," Biggar says.
There have been numerous tape backup technologies implemented in the enterprise, but the objective has always been the same -- achieve maximum capacity and performance with minimum cost. The LTO family has gained tremendous traction over the last few years, bolstered by its open nature and support from industry giants like IBM, Hewlett-Packard Co. (HP), Quantum Corp. and Tandberg Data. Today, LTO-3 has emerged as one of the most important tape formats, offering 800 GB of compressed storage per cartridge and compressed data rates of 160 MBps. "Right now, it's all about LTO-3. It's very popular, almost ubiquitous. It has displaced DLT in the enterprise as the primary compact/small tape device," Abraham says. LTO-4 provides 1.6 TB of compressed storage per tape and should support compressed data transfers to 240 MBps. LTO-4 is expected around mid-2007 and will probably be available from all four vendors by the end of 2007. Encryption will be a common option in LTO-4 drives, allowing users to protect tape data without the need of encryption features in backup software.
Abraham segregates today's tape backup systems into three categories. A low-end tape system typically includes one tape drive and some form of basic autoloader that is normally limited to 10 cartridges or less. A midsized tape library is common in the enterprise, using four tape drives with autoloading space for up to several thousand tape cartridges. For example, a four-drive system with an 80 cartridge library is common, with prices in the $30,000 to $80,000 range. For the large enterprise, Abraham suggests a much larger library with up to 64 tape drives and the robotics necessary to swap tapes from a library of 5,000 cartridges or more.
Tape reliability and life expectancy
Tape has garnered a reputation for poor reliability, but this is a notion that experts are quick to debunk. "It's not unusual to see data reliability specified at one million hours right now," Abraham says, noting that some vendors call this "power-on hours" with 25% to 50% tape motion. Some tape cartridges have been certified to retain data for upwards of 30 years -- even up to 50 years on premium media.
So, why do tape backups seem to suffer from such poor recoverability? Experts say that recoverability problems are not in writing to the tape. "The tape drive records information when it's told to do a backup or an archive, and it verifies that the information is recorded properly at the same time its recording -- disk drives don't do that," Abraham says. Both Abraham and Biggar suggest that the problem isn't in the tape cartridge or drive, but rather in other tangible errors or oversights, such as operator errors, backup software bugs, changed/incompatible backup software versions, lost or mislabled tapes and poor tape storage conditions.
Implementing tape backup platforms
A tape system typically consists of four elements: the tape drive or library, the backup software, the backup server, which runs the backup software, and the tape cartridge(s). Although there is considerable flexibility in the choice of these four elements, experts note that the single greatest concern is backup server performance. It's crucial that the server be faster then the tape drive so that a steady stream of data is always available -- if the data buffer empties, the tape drive must stop and reposition the tape before more data can be written. This results in a repetitive back and forth motion of the tape called "shoeshining," which puts excessive wear on the tape and shortens its working life. Many LTO-3 drives can track to slower servers, but this is a waste of potential performance. Experts urge full-speed operation to get the most possible value from tape backup investments.
When deploying a tape backup system, it's important to plan for future growth. Since forklift upgrades can be extremely expensive and disruptive to the backup process, experts suggest selecting a tape platform that can accommodate growth with relatively inexpensive upgrades. For example, a user needing 40 cartridges might select a tape library with a 120 slot capacity, then incrementally add to the remaining 80 slots over time as needs change. Similarly, a user might select a tape library with bays for six tape drives, but only install two tape drives to start. The remaining four drives can be added over time to boost recording performance. Another way to increase both capacity and performance later on might be to upgrade the tape drive and cartridge types. "For example if you're using LTO-3 right now, at some point in the future you simply upgrade everything to LTO-4," Abraham says. "You don't have to replace the robotics."
Cartridge handling and management is another area where experts suggest added attention. With an increasing emphasis on security, data encryption should be used wherever possible. While encryption is primarily a software-based feature at the moment, Abraham notes that the LTO-4 standard will support native encryption at the drive itself, and DLT vendors will also be adding encryption on their high-end offerings. Tape backup cartridges can become difficult to manage, especially as the library size scales. RFID technology is also being introduced from vendors, like Imation Corp. to track and locate tape cartridges, or to identify tapes quickly within a library. Secure offsite storage should not be ignored.
The impact of tape backup
Experts and users all stress that tape backup does exactly the same job that it always did -- economically protect enterprise data over the long term.
For home furnishing retailer R.C. Willey Home Furnishings in Salt Lake City, the need to maintain accounting, inventory and other business data for auditors has been a challenge not met with disk storage. The company currently supports about 10 TB of data, though only about 2 TB is considered "production data" located on an EMC disk subsystem. The production data is backed up daily, with full tape backups performed on a weekly basis. "We don't believe in incremental backups," says Richard Sheridan, IT manager at R.C. Willey.
Sheridan uses an aggressive array of tape storage to address backup needs. One SpectraLogic Corp. Python T950 and two Python T120 tape libraries handle the local tape backups. Three SpectraLogic Python T50s support remote backups at remote distribution centers. To make the backup process as unobtrusive as possible, backups are staged to EMC business continuance volumes (BCV) and staggered to four SAIT drives in the T950. "We're taking backups throughout the day," Sheridan says. "At any given time, we could have three or four backups happening." The daily tape backups are also performed twice, so one copy is kept onsite, while the duplicate tape is carried to a fire safe nearby location. With four hours to backup 500 GB, Sheridan estimates the total daily backup window runs between eight and 10 hours. Security concerns are met by encrypting the backup data at the server.
This daily backup strategy yields a recovery point objective (RPO) of 24 hours, though the recovery time objective (RTO) is considerably shorter. "I can take my whole production environment and put it back on a BCV in four hours." Shreidan says, noting that tapes are available back to January 2000. Recovery testing is an ongoing process, and Sheridan typically restores one tape per week to locate lost files. Recovery is tested more formally on a monthly basis by restoring to the company's disaster recovery site 45 miles to the north.
The SAIT drives were a big improvement over older DLT technology, but Sheridan is eagerly anticipating future tape drive upgrades. "We're staying on tape with LTO-4," he says. "With SAIT, it's probably a dead end." The ultimate goal is capacity, and 800 GB (compressed) per LTO-4 tape makes the economics and management needs of tape media far more appealing.
Compliance issues
Long-term backups are also important in the gaming industry, and American Casino and Entertainment Properties (ACEP) must be able to furnish gaming data demanded by regulators. "All gaming-pertinent data has to be stored for seven years," says Aaron Perez, ACEP IT network manager. "We have huge safes full of tapes." Complicating matters even further, recent company acquisitions have caused ACEP's data to rocket from 8 TB to 20 TB in the course of just a year -- nightly tape backups were just not adequate.
Today, 20 TB backup jobs are first staged to Dell Inc. PowerEdge 1950 servers and onto two Dell PowerVault MD1000 disk platforms before being sent to an Overland Storage Inc. NEO 8000 tape library with six LTO-3 tape drives, each running about 50% of the time. "It's not all backed up at the same time," Perez says. "We have three or four backup servers running concurrent backups and dragging everything to tape." There are currently 200 tapes in the NEO library, but Perez rotates about 10 to15 of those tapes to the library each month.
The ability to take tape backups off site is a key element of the ACEP disaster recovery strategy. Perez relies on a NEO 4100 tape system located in another casino for emergency recovery. Efficiency is also a major aspect of tape economy, and Perez points out that the move to 400 GB (uncompressed) LTO-3 from older 50 GB AIT-2 tapes lets ACEP save far more data per tape in less time.
RTOs vary depending on the system that needs to be restored, but Perez notes a documented RTO of eight hours for "minimum usability." Slot systems with 80 GB to 100 GB of data may take far less time to recover, while email systems with 400 GB to 500 GB will take considerably longer. Recovery testing, however, is usually an ongoing process. "We test regularly when we have to restore a lost user file -- that happens three or four times each week," Perez says, adding that formal biannual testing also helps to verify the recovery process.
Looking toward the future, Perez expects to expand the NEO 8000 with additional tape slots, drives and servers, though a migration to LTO-4 isn't in the immediate roadmap. "I'd consider it, if the cost is right. But then you'd have to do a full overhaul [of the tape system and process]." The big dilemma for ACEP now is tape encryption, though Perez isn't yet satisfied with the capabilities of encryption in backup software. "Some software manufacturers aren't stepping up to the plate."
The future of tape backup
The demise of tape backup has been predicted for years, especially now that disk technologies, like continuous data protection (CDP), snapshots, replication and virtual tape libraries (BTL) have emerged in the data center. Still, experts are quick to emphasise that many disk technologies are basically used for buffering tape -- removing the backup burden from primary disk. Experts also underscore the benefits of mobility and long-term retention, noting that tape's reputation for questionable reliability is undeserved. "It's very easy to verify recorded data as you write it, so the reliability is never affected as it might be with disk," Abraham says.
The current market is stable, due in part to the current investments made in tape technology, and experts see LTO vendors with sales growth in the high single digits. "The total market size on average seems to be at a steady state or a slight increase," Abraham says. "That overall trend will probably continue for about five years." Experts say that the future of tape backup lies with the open, performance-oriented technologies, such as LTO. The eventual release of LTO-4 should support an incremental increase in storage capacity and speed, and the inclusion of encryption in the drive itself should attract attention from storage organisations concerned about security and compliance issues. The entire LTO roadmap promises growth to 6.4 GB of compressed storage with transfer rates to 540 MBps. "LTO is not on its deathbed," Biggar says.

Whats Behind cheaper Printer Ctgs ?

What's Behind Cheaper Printer CartridgesH-P, Kodak, Others SlashPrices but Also Volume of Ink;A Higher Cost per PageBy CHRISTOPHER LAWTONMay 9, 2007; Page D1
Printer makers such as Hewlett-Packard Co. and Eastman Kodak Co. have recently introduced cheaper printer-ink cartridges priced at around $15. But consumers may find that paying less at the cash register ends up costing them more in the long run.[Photo]Lower-price cartridges from Eastman Kodak ($9.99) and Hewlett-Packard ($14.99).
That's because there is less ink in some of the new cartridges, so the cost of each page printed is actually higher. Also, some of the printers that accept the new lower-priced cartridges cost more than other printers.
Companies are rolling out lower-priced cartridges as they increasingly compete with the growing market of "remanufactured" or "refilled" ink cartridges. Printer makers such as H-P have long sold printers for little or no profit, making up the loss from ink sales. But that business model has recently come under pressure from discount players such as Cartridge World, a chain store that refills empty ink cartridges, and large office-supply stores, such as Staples Inc. and Office Depot Inc., that sell their own brands of remanufactured cartridges. Many refillers offer cartridges at prices up to 50% less than those of big printer makers. By 2010, refilled and remanufactured ink cartridges are projected to account for 37% of the world-wide ink-cartridge market, up from 29% in 2003, according to Lyra Research Inc.
H-P, the largest U.S. printer company, late last month unveiled new black-ink and color-ink cartridges for $14.99 and $17.99, respectively, or 25% and 28% less than previous comparable cartridges costing $19.99 and $24.99, respectively. In February, Kodak rolled out a $9.99 black-ink cartridge and a $14.99 color-ink cartridge. That same month, Canon Inc. released a new black-ink cartridge for $15.99 and a new color cartridge for $19.99, down from $19.99 and $24.99 respectively.
But a closer look at some of the new cartridges reveals that consumers may be paying higher prices for their printer ink over the long run. In one comparison, an older H-P standard black-ink cartridge contained 11 milliliters of ink, while the new standard cartridge has just 4.5 milliliters of ink. As a result, the cost of printing with the new H-P black-ink cartridge rises to 7.5 cents a page from 4.4 cents a page for the older cartridge, according to Lyra.
Canon's new ink cartridges also come with less ink than their predecessors. Canon's new black-ink cartridge contains 11 milliliters of ink, down from 16 milliliters in the old version. That bumps up the cost of printing per page to 6.7 cents from 5.6 cents previously. Canon's new color-ink cartridge contains nine milliliters of ink, for a printing cost of 15.4 cents a page, versus 12 milliliters previously, for a cost of 13.7 cents a page.
Meanwhile, Kodak's $14.99 and $9.99 ink cartridges are tied to the launch of several new Kodak printers, which are priced higher than other printers. Kodak's printers cost $150 to $300, or around $50 more than some comparable models by rivals.
Many printer makers now want to appear to match the refillers' prices in order to better compete, analysts say. Charlie Brewer, a Lyra analyst, says printer companies started introducing ink cartridges in the $15 range in 2005, following the launch of cheaper, refilled cartridges from office superstores such as Staples and Office Depot. "Companies understand that consumers are getting miffed at the amount they have to pay for cartridges," says Mr. Brewer.[Ink]
Some printer executives acknowledge the new $15 cartridges won't lower consumers' costs. "There will be cases where [the cost of printing per page] goes up" with the new H-P cartridges, says Pradeep Jotwani, who heads the supplies business for the Palo Alto, Calif., company. But he argues that offering the lower-priced cartridges gives choices to consumers who don't print much and who simply want to save money on the upfront purchase.
H-P has also introduced some "higher-yield" cartridges for people who print more and for whom cost per print is more important, Mr. Jotwani notes. He says there are some cases where the cost of printing per page ends up decreasing. In one example, H-P's new color-cartridge with 12 milliliters of ink can be measured against an older cartridge that contained five milliliters of ink. In that instance, the cost per page drops to 6.7 cents from 9.5 cents previously, says an H-P spokeswoman.
Michael Duffett, a Canon director of inkjet printer marketing, also says customers who don't print much will benefit. "With the [small] amount of prints being made by this audience, initial ink purchasing cost becomes a stronger motivation over cost per print," Mr. Duffett says.
The new cartridges are forcing at least one seller of remanufactured ink cartridges to cut back. In February, Staples decided to stop selling its lower-priced Staples-branded ink cartridges that work with H-P printers, which were manufactured by Inkcycle Inc., an ink and toner manufacturer based in Lenexa, Kan.
Scott Rankin, a Staples vice president, says H-P's new cartridges made it too difficult for the retailer to continue stocking its own remanufactured cartridges since the retailer couldn't match H-P's technology in each of the new offerings. "It introduced a new level of complexity into the system," he says. He adds that Staples will consider whether it makes sense to discontinue its Staples-branded cartridges for other vendors apart from H-P.
Still, printer makers have a way to go in persuading consumers to buy their ink. Talal Itani, who owns an electronics design business in Plano, Texas, purchased a color Canon printer three years ago and has bought Canon-branded ink cartridges to print letters, pictures and his children's homework. To replace the ink cartridges, Mr. Itani says he typically paid $44. So last month, Mr. Itani went online and ordered new cheaper cartridges made by Pro Color Technology Ltd., a Hong Kong-based remanufacturer. The total price: $10.46.
"I was surprised by the quality" of the ink, says Mr. Itani, 46 years old, which he felt was "very good." Mr. Itani adds that he's not interested in Canon's new standard cartridges, even though they appear to be lower priced. "What interests me is how much I can print per dollar," he says. "If they give me a big cartridge with little ink in it, that isn't going to help me."
