Acer Aspire S3 Review

January 20th, 2012

The Acer Aspire S3 looks very nice in the product photos, and it is often associated with Ultrabooks because this type of design, which is inspired from the Macbook Air, has been used by many PC manufacturers in their recent designs. I like the new look very much, and I have been pretty bullish about Ultrabooks, at least much more than I ever was about Netbooks. Although Ultrabooks often share a similar hardware platform from Intel, they differ more than one may think, and depending on how they were designed, the end-user experience can be very different from one model to the next, so don’t let the superficial resemblance fool you. In this review, I will tell you how it felt to use the Acer Aspire S3 and we will look at what I felt was its strengths and weaknesses.

Industrial design

The Acer Aspire S3 Ultrabook has an agreeable design. It is thin, compact, and light. The loaner unit that we have even has a custom paint job that was done for Intel. The case seems to be built with a Magnesium alloy, which is a classic material for laptops and notebooks. Overall, it feels rigid enough, but there is a little bit of “flex”, especially with the display – it’s not as flexible as the Toshiba Ultrabook Z830 whose screen is *very* flexible, but we’re definitely not in the rigidity territory that the Macbook Air or Asus Zenbook are in.

In the back of the computer, you will find one HDMI port, two USB 2.0 ports, and the power connector. This is a good placement if you mainly use the computer on a desk as there won’t be any cables popping out from the sides, but if you need to plug and unplug things regularly, this may be a bit annoying. For example, we often use a 3G USB modem, and with the USB port in the back, it is possible (or probable) that backwards tilting would apply pressure to any USB device. You’ll have to think about this a little, and decide what works for you.

Because most of the ports are in the back, the sides are left clean with just a 3.5mm audio jack (left) and a full-size SD slot on the right (see photo gallery at the bottom).

Overall, I found the build quality to feel a bit “plastic”, and I think that Acer should improve upon this, because with its XPS 13 Ultrabook ($999 with 128GB SSD), Dell has a much nicer (partial) carbon-fiber construction and a better “soft touch” finish wherever carbon-fiber is not used. The HP Envy 14 Spectre (see Envy Spectre 14 demo) is also extremely nice, and the build quality is even higher than the XPS 13. However, it is much more expensive, and at 4+lbs, it is heavier.

Keyboard (average, no back light): for the most part, the keyboard is decent and there are no major complaints. The only thing that should really be different are the arrow keys. They feel tiny, because they *are* tiny. I don’t know for you, but if you type a lot of text, chances are that “Shift/CTRL + arrow” is a pretty big deal because that allows one to quickly navigate within a sentence. Also, I wish that there was a backlit keyboard, but this is not the case. Again, some people care, while others don’t. Find out in which category you stand.

Trackpad (above-average): The trackpad is “OK”. It’s not super-smooth, but it’s better than most trackpads, so I would say that it is above-average, but, not quite high-end or anything like that. It gets the job done and is definitely good enough and big enough.

Display (average): the display is OK, especially If you look at it straight-on. The view angle is not great and colors start changing rapidly as you move around, but this is a widespread behavior for computers in this category. What I like the most about the display is the ability to recline very far back. This can be great in airplanes or in other situations where you need that extra tilt that most laptops don’t have. This is definitely a plus.

In terms of processing performance, the Acer Aspire S3 processor does fairly well. For instance, when compared to my first generation Macbook Air, it is about 2X as fast in raw performance, which is as fast as the Samsung Series 9, according to Geekbench.

That said, I have to stress that synthetic benchmarks don’t tell the full story. Perceived performance is much more important to the end-user, and things like pre-loaded software (bloatware) or a slow disk can affect performance drastically. Here, the 5400rpm drive clobbers the end-user experience when compared to SSD-equipped competitors. The boot time and shut down speed is 5X or 6X slower, and the overall system responsiveness is lower as well.

Boot/wake-up/shut down speed

Shut down: 48 sec
Boot to browser: 60 sec
Wake-up from sleep: <2 sec
Battery life (fair)

For these tests, I have adjusted the power settings to make sure that the user experience is good enough. For example, the computer can play the test .mp4 1080p movie in Power Savings mode, but YouTube required switching to the more demanding Balanced Mode in order to get a smooth frame rate.

60mn of 1080p MP4 video playback used up 29% of the battery (download it here: gt5rpe3trailer_fixedv11_1080.mp4)

60mn of 1080p Youtube playback (WiFi) used up 40% of the battery (actual video: http://www.youtube.com/watch?v=_dJCLaoBZvM)

60mn of doing nothing (Display at 50%, no apps running) used up 18% of the battery. This is very important because this means that in the best-case scenario, the computer can stay on for about 5hrs, which is fairly good, but there are better options.

Charge time: recharging is as important as the battery life itself, because a quick charge can make a world of difference. It is clear that battery capacities won’t increase dramatically for any given size, but rapid-charging is already a working solution for industrial purposes, so consumer electronics will be next. to reach a full (100%) charge, the Acer Aspire S3 takes about 2 hours and 45 minutes, but if you are on a clock, stop at 90% (1hr 50mn) because that’s when things start to slow down dramatically. This is not uncommon for batteries, but depending on laptops there are different behaviors, so it’s definitely worth checking out.

In the end, the battery life is fair, and it’s surprising what one can get out of a 3-Cell battery these days. You can watch 3 hours of 1080p video, and that’s a fair amount for a laptop. Tablets can go as long as 10 hours, but it’s clear that they don’t have the chops to run more demanding Windows applications. Also, most (older) laptops in circulation now would probably die shortly after the first hour of 1080p video.

Misc

Webcam: the webcam quality of the Acer Aspire 3 is relatively low, which is unfortunately quite common in laptops. Even in good lighting conditions, the response time/frame rate is low, so I am guessing that the camera is slowing the shutter speed to compensate for the lack of light sensing capabilities. It’s never a good sign.

Audio: the speaker quality is pretty good, especially for a laptop this size. In a quiet environment, watching a movie, or listening to music is enjoyable. In a noisy environment (trade show, noisy cafe…) this could be more challenging.

Conclusion (needs to kick it up a notch)

The Acer Aspire S3 is an interesting laptop, which delivers good raw compute performance that is comparable to other laptops using the same Intel Core i5 24xx platform. However, the choice of using an mechanical hard drive (HDD) will put it at a significant disadvantage when compared to competitors who have opted for a Solid State Drive (SSD) because the SSD seek-time is nearly infinitely faster. SSD is a critical component of perceived performance in a computer. If you can afford one, get one.

If Acer could justify it with a much lower price point, there would be some grounds for debate. However, Dell has an offering that is just $100 higher and features a smaller form factor, a better display, a 128GB SSD, better build quality and… USB 3.0.

Interestingly, some competitors don’t offer the HDD option at all, so if you need a lot of storage (300GB+), and/or want to save a buck, the Acer Aspire S3 can be a slightly cheaper option. My personal take on this is that if you *really* need more than 128GB, you way want to consider a laptop with an SSD drive and use USB 3.0 for the additional storage.

In the end, the Acer Aspire S3 does look good, but in the current competitive landscape, this computer should be priced at $749, and not at $899. If you are willing to spend close $1000, there are simply much (much!) better options out there. I hope that this Acer Aspire S3 review has helped you form an opinion about this computer. If you still have questions, please leave a comment, and I will try to address it asap.

Adding a solid state drive to your computer

November 14th, 2011

If you want to give your computer a speed boost, you should think about flash drives. If you want something affordable, you need to stick with tried-and-trusted hard drives. Or you can try to have the best of both worlds and install both in your computer.

The trick is splitting the load, so the operating system and frequently accessed programs are stored on the flash solid state drive (SSD), a more modern form of drive that boosts speed by allowing all data to be accessed simultaneously, as opposed to magnetic drives, which can only give up their information as they are read front to back.

Everything else goes on that old-fashioned drive. ‘The speed gain through SSD is enormous,’ says Christof Windeck, a hardware expert for the German computer magazine c’t.

You don’t have to be an expert to install an SSD drive into a PC. Most SSD drives are produced in a 2.5-inch format, meaning you’ll need a 3.5-inch case so it fits into the PC. Those cases usually come with any SSD drive you might order.

Laptops are a little trickier, since space is limited. You might have to decide if you can do without your optical CD/DVD drive, since that function could be provided by an external device. If you make that plunge, you’ll have freed up space for an SSD drive, which also needs to be fitted into a special frame to fit into a laptop.

‘Installation is no problem,’ says Wolfgang Hantz, who owns a hardware upgrade company in Germany. ‘Even a beginner can do it.’

Alternatively, set up the SSD as your boot-up drive, using the freed-up hard drive space for your optical drive.

An SSD with about 100 gigabytes (GB) costs about 120 euros (167 dollars) at online stores. Windeck says it doesn’t make sense to get one with less than 80 GB if you’re planning to run Windows 7 and have a slew of space-consuming applications.

There are quality differences between different kinds of SSD. ‘If you can afford it, you should consider an SLC-SSD,’ advises Daniel Mauerhofer, of hard drive maker Western Digital, referring to a Single Level Cell model. ‘These last much longer than multi-level cell drives and have better performance,’ he says.

Then there’s the hybrid solution of a magnetic hard drive with an integrated SSD, like the kind Acer has built into its ‘ultrabook,’ the Aspire S3. The 20 GB flash drive complements the 320 GB magnetic drive.

This kind of hybrid is also available for sale as an individual building block. There’s the Momentus XT from Seagate with a capacity of between 250 and 640 GB, with the integrated 4 GB SSD drive acting as a buffer for vital data.

Even if you don’t want to check out SSD drives, you might still find yourself needing to explore the hard drive market, especially if your computer crashes. ‘The hard drive market has changed,’ explains Windeck. ‘For years it was all about performance, now there’s an eye on energy conservation.’

The fastest magnetic drives, with 10,000 to 15,000 rotations per minute, are mostly targeted at gamers, though some large companies need drives like that, says Mauerhofer. Windeck says there are advantages to slower drives: ‘They don’t get as hot, need less ventilation and are quieter.’

Also keep an eye on whether a drive has a modern SATA connector. Avoid a drive with the older IDE technology, advise the experts at c’t magazine.

To get at your notebook’s hard drive, you usually just need a screwdriver to remove a plate on the bottom of the machine.

Another option is to boost your working memory. Getting at that is also a simple operation. SDRAM memory modules with Double Data Rate (DDR3) are the most modern and, according to Windeck, usually cheaper than the older DDR2 standard. Neither standard is compatible with the other, because they use different housings.

You can usually boost speed by adding more working memory. But before you start refitting your motherboard, compare the cost of getting new RAM with that of getting a new computer. Often, and just for a little more money, you can get a brand new computer with all the latest technology.

And remember, 4 GB is usually enough. ‘If you only have 2 GB of working memory, then it makes sense to expand to four,’ recommends Windeck. ‘But an expansion from 4 to 8 GB only helps a very few applications.’

An Old Hard Drive and OS in a New PC

May 27th, 2011

Terry Marshall asked if he could move his old hard drive, unchanged, to his new home-built PC, boot his existing, “very stable” XP installation, and skip Windows 7 altogether.

The short answer is no. Here’s why:

Windows is a very hardware-specific operating system. When you install it onto a computer, it configures itself for the hardware. Unless the two PCs are physically identical, taking the hard drive out of one and using it to boot another is asking for trouble. The result will be very unstable–if it runs at all.

If your computer didn’t come with Windows pre-installed, you must install the OS from scratch. And then you have to install your applications and move over your data.

There’s another issue: Microsoft puts limits on what you can do with a single copy of Windows. If it suddenly appears to be running on new hardware, it will object.

Does that mean you have to give up your beloved XP? Not necessarily. If you installed a full, retail copy of XP onto your old computer, you can use the same CD to install it onto your new one. The installation program will probably object when you enter the license number, because the copy is on another computer, but you can call the provided 800 number and explain the situation.

As long as you promise to remove XP from the old computer in the near future, and keep that promise, there should be no trouble.

But if XP came with the old PC, the license is strictly for that computer. You can’t transfer it. You can, however, still buy XP–even if Microsoft is no longer selling it. A Google Shopping or Pricegrabber search will bring you plenty of choices.

Sony SDT-11000 Tape Drive Is a Smart Choice for DDS 4 Backup Media

April 14th, 2011

Increasing number of regulations and data retention laws have forced the companies to secure and preserve their corporate data. The data administrators are turning to DDS (digital data storage) technology, which is ideally designed to support information systems, small and medium organizations, demanding enterprise applications, workgroups and workstations. Sony, the market leader in tape-based backup technologies, has developed a complete fourth generation DDS-4 tape solution to help solve the storage challenges. Sony DDS 4 tape solution offers large capacity, fast speed and superior performance in data intensive applications.

SDT-11000 is a high-speed DDS-4 tape drive that has been specifically developed by Sony to support DDS4 tape media. Sony SDT-11000 drive uses helical scan technology for read/write operations. Helical scan mechanism has dramatically improved the recording density. Throughput rate of SDT-11000 tape drive has been enhanced to 4.8MB/sec (compressed), which is 100% higher than that of DDS-3 tape drive. DDS-4 tape cartridge’s size is relatively smaller than other tape cartridges in its class. Up to 40GB compressed data can be packed onto a tiny DDS 4 backup tape.

Sony DDS4 cartridge delivers outstanding durability and higher operating efficiency that is demanded by today’s IT environments. Sony DDS 4 tape’s strong cartridge shell protects against inadvertent drops. Therefore, the users can transport the Sony DDS 4 tapes to off-site locations without any fear of cartridge damage due to shocks or bumps. SDT-11000 drive has the amazing capability to read & write all the previous generation DDS media. It is compatible with four versions of DDS ranging from DDS-1 to DDS-4.

Sony has introduced SCSI-3 Ultra Wide/LVD interface, which has enhanced the compatibility of SDT-11000 drive to a broad range of IT environments. Backup rate of SDT-11000 drive increases to 17.28 GB per hour in compressed mode. It performs high speed searching at an impressive speed of 360 MB per second, which makes it the prefect tape drive for time-critical applications. Architecture of DDS 4 cartridge has been redesigned by Sony to help increase its robustness, cartridge strength and allow smooth tape movement. Price of Sony SDT-11000 drive and DDS 4 cartridge is competitive.

Airborne pollutants can degrade the recording performance and cause read/write errors. An intelligent SAFE (Super Air Flow Environment) design has been introduced by Sony in SDT-11000 drive to prevent dust accumulation. This unique design improves the airflow through the drive specifically over the tape path area. In addition, it also helps to lower the temperature of drive components.

OCZ Vertex 3 Series solid-state drive – 480 GB – SATA-600

April 14th, 2011

The good: The OCZ Vertex 3 solid-state drive supports SATA 6Gbps and offers very fast performance and up to 480GB of storage. The 2.5-inch internal drive comes with a mounting accessory to fit in desktop computers’ drive bays, and is comparatively affordable.

The bad: The OCZ Vertex 3 SSD is significantly more expensive than traditional hard drives, particularly the 480GB-capacity model, and takes a long time to format.

The bottom line: With excellent performance, the OCZ Vertex 3 SSD makes an ideal internal storage drive for laptops and desktop computers, especially those that support the 6Gbps SATA standard. Its hefty price tag will make most consumers think twice, however.
Review:

The OCZ Vertex 3 solid-state drive is the second SSD (after the Plextor PX-256M2S) we’ve reviewed that supports the new 6Gbps SATA 3 standard. Like the Plextor, the OCZ showed stellar performance in our testing, enough to justify the $500 price tag for the 240GB version or the $250 for the 120GB version. Its 480GB version, however, is outrageously expensive at $1,800.

If your computer, be it a Mac or PC, supports SATA 3, then the OCZ Vertex 3 makes a worthwhile investment and will increase the computer’s performance significantly. The drive also works with the existing … Expand full review

The OCZ Vertex 3 solid-state drive is the second SSD (after the Plextor PX-256M2S) we’ve reviewed that supports the new 6Gbps SATA 3 standard. Like the Plextor, the OCZ showed stellar performance in our testing, enough to justify the $500 price tag for the 240GB version or the $250 for the 120GB version. Its 480GB version, however, is outrageously expensive at $1,800.

If your computer, be it a Mac or PC, supports SATA 3, then the OCZ Vertex 3 makes a worthwhile investment and will increase the computer’s performance significantly. The drive also works with the existing and popular 3Gbps SATA (SATA 2) controllers and at a much faster speed than regular hard drives. However, for SATA 2, you should also consider the slightly cheaper Samsung 470 hard drive.

Like the Samsung 470, the OCZ Vertex 3 has the same shape, dimensions, and port design as any standard 9.5-millimeter, 2.5-inch internal hard drive. The drive also includes a drive bay converter to take the place of any 3.5-inch hard drive. This means it will work in any case where a traditional SATA hard drive would be used.

The drive supports the latest SATA 3 (6Gbps) and also works with SATA 2 (3Gbps), as these two standards use the same interface ports. Obviously, if you want to get the best performance, the former is recommended.

We tried the Vertex 3 with a few computers of different platforms (Mac, Windows, and Linux) and it worked well with all of them. We did notice that the Vertex 3 took a significantly long time to be formatted compared with other drives. In our trials it took about 5 minutes to be quick-formatted using Windows 7. Other drives, even those that are really large in capacity, would take just less than a minute.

The OCZ Vertex 3, like all SSDs, uses flash memory chips as its storage rather than the platters used in traditional hard drives, and therefore has no moving parts. This means it uses much less energy and is more resistant to shock and vibration. It’s also much lighter than hard drives of the same size. The OCZ Vertex 3 is heavier than the Plextor PX-256M2S or the Samsung 470, however, as the bottom part of its casing is made of aluminum, not plastic, making it seem sturdier than its peers.

Cost per gigabyte
As expected, the OCZ Vertex 3 is significantly more expensive than traditional hard drives, such as the hybrid Momentus XT. At about $500 for just 240GB, the Vertex 3 costs around $2.08 for one gigabyte. The Momentus, which is the most expensive among both traditional and hybrid hard drives, costs less than 10 cents per gigabyte, making it more than 23 times cheaper. This figure can go even lower with regular hard drives. The 3TB Seagate Barracuda XT, which offers the most storage on a single drive to date, costs just 8 cents per gigabyte.

When compared with other SSDs, however, the 256GB Vertex 3 is currently one of the most affordable, just slightly more expensive than the Samsung 470, for which the cost per gigabyte is $1.95. The Samsung doesn’t support SATA 3, however.

Performance
We tested the OCZ Vertex 3 thoroughly with many different applications and it performed excellently with all of them. We used the drive both as the main drive of the test machine, running Windows 7 64-bit, and as a secondary backup drive.

When the drive is used as the main hard drive that hosts the operating system, the tests are designed to gauge the computer’s performance as a whole. For this reason, the hard drive only plays a small role in the final score. Nonetheless, the test machine showed a visible difference in performance contributed by the OCZ Vertex 3.

We compared the OCZ Vertex 3 against a few SATA 3 SSDs and hard drives on the market, including the 3TB Seagate Barracuda XT and the Plextor PX-256M2S.

In the boot-time test, the OCZ took a very short time, just 29.1 seconds, a tad slower than the Plextor’s 28.2 seconds, and significantly faster than the Seagate’s 48.2 seconds. Note that this boot time includes the time the test machine spends going through the hardware initialization, which already takes about 15 seconds. For shutdown speeds, the OCZ topped the chart with just 5.8 seconds while the Barracuda took twice that amount of time.

In the Office Performance test, in which we time how long the computer takes to finish a comprehensive set of concurrent tasks including use of Word and Excel, file transferring, and file compression, the OCZ took the first place at just 338 seconds, followed by the Plextor and Seagate, which needed 383 seconds and 391 seconds respectively.

It seems the drive’s speed doesn’t affect the speed of music conversion much, as on the test machine it took exactly the same amount of time for all three drives to convert music from MP3 to AAC format using iTunes. However, it was a little different with our multimedia multitasking test, which gauges the computer’s performance when it converts a hi-def movie from one format to another while iTunes is doing a heavy job of music conversion in the background. In this test, the OCZ Vertex 3 was again the fastest, though it beat the other two by only a few seconds.

We test a storage device’s throughput performance by timing how long it takes to finish copying a large amount of data from one place to another. Both as the main drive and as a secondary backup drive the Vertex 3 was very fast, at 150.01MBps and 260.71MBps, respectively. These numbers beat those of the Barracuda XT, which scored 51.1MBps and 115.71Mbps as a main and secondary drive respectively, by a huge margin. Note that these are real-world sustained throughput speeds after all the software and hardware overheads.

All in all, we were very happy about the OCZ Vertex 3’s performance. Using it as the main drive increased our tested machine’s overall performance significantly and applications loaded much faster. And the computer was able to wake from sleeping instantly.

Service and support
OCZ Technology Group backs the Vertex 3 with a three-year warranty, which is a decent deal, similar to what you get for the Samsung 470 and the Plextor PX-256M2S. When it comes to storage devices, the length of the warranty is the most important factor and it would be even better if the company offered a five-year warranty as in the case of the Momentus XT.

Conclusions
As with the Plextor PX-256M2S, the OCZ Vertex 3’s hefty price keeps us from naming it an Editors’ Choice. However, the Vertex 3 is an excellent replacement drive for a desktop or laptop, especially one with built-in support for SATA 3. The OCZ Vertex 3 will help you get the most performance out of your high-end system.

Deerfield CITGO Holding Computer Recycling Drive

April 13th, 2011

A computer recycling/donation drive will also be taking place at a “green-certified” CITGO station in Deerfield, Ill., on April 30 and May 1. United Way of Lake County (UWLC) is working to recycle computers for families who need them in Lake County. UWLC, in conjunction with local partners, is repurposing used computers for Waukegan High School families enrolled in the Computer Learn & Earn initiative in order to close the “digital divide.”

The station is owned by Dave Welsh, who is a part of the Waukegan School District. Anyone that donates a computer during the CITGO drive will receive a free fountain drink. Donation/tax forms will also be available.

UWLC is seeking laptops and towers, keyboards, cables, printers and any other computer hardware, flat-screen monitors, laptop bags and mice. All computers are wiped clean of personal information. It is also looking for volunteer computer refurbishers.

The organization discovered through focus groups and research that many Waukegan families lack a home computer; others do not have technological skills. Parents that participated in the Computer Learn & Earn classes now have both, and their children now have access to an increasingly important homework tool. Volunteers from Abbott Laboratories teach parents how to operate a computer and perform basic tasks. Then, parents are introduced to District 60’s Infinite Campus computerized records system, which allows parents to check their child’s attendance and academic performance online. In the final session, parents receive information they can use to help their children succeed in school and go on to college. To date, over 75 computers have been given to Lake County families in need. UWLC hopes to receive 200 computers through the computer donation drive at the CITGO station.

Computers are donated by various companies and individuals, and are refurbished by Microsoft Registered Refurbisher volunteers. The computer packages include a monitor, keyboard, mouse and Microsoft Office software.

Seagate ships 3TB desktop drive, breaking 2.1TB barrier

March 2nd, 2011

Seagate Tuesday released its highly anticipated 3TB desktop hard disk drive, the 3.5-in Barracuda XT, thus eliminating the need to purchase extra hardware or software to overcome the previous 2.1TB drive barrier.

Last spring, Seagate had said it would ship its first 3TB HDD, the Constellation ES, by the end of 2010. That drive, for data center servers, has yet to ship.

Western Digital came out with its first 3TB internal desktop drive in January, the Western Digital Caviar Green. Western Digital had its own workaround for the 2.1TB limitation: a HighPoint Rocket 620 internal half-height SATA card, which it ships with the 3TB drive. The card has two SATA 3.0 ports and handles the emulation, if needed, to allow software to work with the larger 3TB hard drive.

Seagate said it was able to make the drive’s capacity available to PC systems through its free DiscWizard utility. Seagate added a virtual device driver to the utility to allow legacy BIOSes and OSes, such as Windows XP, to access capacity above 2.1TB on a drive. Without the driver, PCs with older OSes and BIOS designs would only be able to create volumes up to 2.1TB.

Hence, the Barracuda XT hard drive now delivers the highest available capacity on a single drive for home servers and workstations, high-definition video editing and production systems, high-performance PC gaming systems and desktop PCs.

The new DiscWizard software is available for free download on Seagate’s website.

The 2.1TB ceiling for internal HDDs was set about 30 years ago when a decision was made to limit the logical block address (LBA) range on a hard drive. The LBA specifies where blocks of data are stored on a hard drive.

Legacy PC BIOS designs and device drivers and older operating systems such as Windows XP are incapable of using hard drive capacities beyond 2.1TB. The upshot is that computers with older platforms can create partitions with up to 2.1TB of storage capacity, but must be deployed with additional software or hardware and may also require extra device drivers to overcome this limitation.

Currently, in order for PCs to recognize drives with more than 2.1TB capacity, they must use the Unified Extensible Firmware Interface (UEFI) standard that Intel and IBM introduced in 2007. The UEFI standard, however, has not been widely adopted.

“We believe UEFI will remain in a nascent category for a bit longer before there is broad adoption,” said David Burks, marketing director for Seagate. “We felt strongly that we needed to create a product that didn’t require UEFI for customers who wanted to use the full capacity of these big drives.”

Burks admits that UEFI will eventually be the solution across the industry for allowing older OSes and system BIOS to utilize high-capacity drives, and that the new firmware upgrade on DiscWizard is merely a “stop gap” measure for now.

Users can install the Barracuda XT in their PCs the same as any other drive, using Windows to format and partition the drive.

If the systems platform is Windows XP, it will only access 900GB of capacity on the drive – the portion above 2.1TB. Windows Vista and Windows 7 will recognize 2.1TB capacity on the drive. Users will then be required to download and install the DiscWizard firmware.

Once installed, the user interface will show two partitions, one with 2.1TB and the other with 900GB capacity, and allow a user to adjust those partition sizes to their individual needs. Users will not be able to create a single 3TB partition.

The new Barracuda XT differs little from its 2TB predecessor. The only real difference is that the drive has five disk platters versus four. Like its predecessor, the Barracuda XT has a 7200rpm spindle speed and uses the serial ATA (SATA) 3.0 interface specification giving it 6Gbit/sec throughput.

The drive’s 64MB cache also adds to its performance.

The drive’s suggested retail price is $274.
