| Seagate Barracuda 7200.8 200GB Hard Disk Drive - Page 1 of 6 |
Seagate Technology is one of THE names you think of when it comes to computer hard drives, and it has been that way for a long time. The company was founded in 1979, and they were actually the first to market a 5.25" hard drive for the PC. Much has changed since the seventies, but Seagate remains at the forefront of hard drive development and technology.
The products provided for this review are some of the latest in Seagate's long line of products, and represent another advancement in drive performance. The Seagate Barracuda 7200.8 SATA NCQ drive, model ST3200826AS, is a 7200 RPM SATA (1.5Gb/s) hard drive boasting a capacity of 200GB, an average seek time of 8 ms, and support for native command queuing (NCQ). Seagate has sent over a pair of these drives for testing the stand-alone performance, as well as in RAID 0 and RAID 1 configurations.
Specifications:
Before jumping into the actual performance, let's look at Seagate's published data on the ST3200826AS, as well as on a drive it will be tested against, the 200GB Barracuda 7200.7 SATA (model number ST3200822AS).

It can be seen from the published data that many performance advances have been made from them 7200.7 to 7200.8 offering of the Seagate Barracuda. Real world testing between these two drives should provide an interesting comparison. Of all the data provided in the table above, perhaps one of the nicest numbers is associated with Seagate's industry leading five year warranty! While many manufacturers are cutting back and offering shorter warranties, it is very reassuring to see a five year warranty provided on an item as critical as a hard drive.
