Seagate Barracuda XT ST32000641AS Preview

On 21 September 2009 Seagate Technology will be the first and only manufacturer to offer a SATA-III 6Gbps hard drive product with the large 64MB cache buffer as the 2TB Barracuda XT ST32000641AS is unveiled. Both combined improvements to burst rate and sustained bandwidth will mark a substantial improvement to the design of Hard Disk Drive (HDD) storage products, and the new technology is expected to give Solid State Drive (SSD) components some serious competition. The Seagate Barracuda XT series is designed for performance enthusiasts such as gamers, as well as small server systems. Additional enthusiast tools, such as the free Seagate SeaTools software, allow users to custom-define firmware parameters to enable performance features such as 'Short Stroke' and noise reduction. In this preview article, Benchmark Reviews reveals some of the improvements introduced with the Seagate Barracuda XT 6Gbps SATA-III ST32000641AS hard drive.

The new 2TB Seagate Barracuda XT ST32000641AS is priced at $299 for launch, and offer a 4-platter 368 Gb/square inch aerial density which is sure to please storage-hungry applications. Seagate's own in-house testing has shown a 47% performance improvement over standard Barracuda drives in non-linear video editing. Early adopters of the SATA-III (6.0GBps) interface will enjoy a new high-bandwidth high-capacity solution, while enthusiasts and gamers will appreciate the 64MB cache buffer; the largest DRAM buffer on any commercial hard drive.

The current Seagate family includes a low-power Barracuda LP, and a mainstream Barracuda 7200.12 hard drive. This new edition to the desktop hard drive family carves out the Barracuda XT for the upper-tier of performance. Benchmark Reviews has had great success with the Seagate Barracuda 7200.11 series in the past, which already rivaled performance from the WD VelociRaptor in some tests, but Seagate plans to drop the 'dot' designation on the 7200 series and simplify their desktop storage family to Barracuda LS, Barracuda, and Barracuda XT.


What to expect from SATA-III 6Gbps (SATA 6G):

  • Not an immediate and dramatic across the board performance change.
  • Cache efficient and intensive applications will see immediate benefit.
  • Application optimization, controller, driver and OS optimization and areal density and other pending HDD technology will combine to push performance higher over the next 2-3 years. Seagate-Logo-250px.png

Since the shortage of hdd's is now supposed to last up to 2 years, the one's still available have become as costly as ssd's. I had to buy a new hdd last week and it cost almost $200 for a 2TB SATA drive. No, not SATA 2 or 3. SATA 1, if there ever was such a thing. It wasn't even OEM, it actually came in a retail box. The WD RE4 2TB drive I wanted costs over $350 now. 2 or 3 weeks ago it was closer to $200.
I think more people will choose ssd'd over hdd's for now and this may help drive the prices of ssd's down to a more reasonable level. I doubt that this will be the end of hdd's because of their massive storage, but I also bought another Crucial M4 256GB ssd last week, too. It turns out that it cost exactly the same as the hdd I actually wanted. The 1st 2 of these ssd's I bought earlier this year were just over $400 each. The prices of ssd'd are coming down while the price of hdd's have skyrocketed.
