| Hitachi Deskstar 7K400 vs Seagate Barracuda 7200.8 400 GB |
|
Hitachi is a company of many products ranging from small things like batteries, to high-end desktop computer components, to advanced medical equipment. For computer enthusiasts though, they are probably best known for their Deskstar hard drive product line. The Deskstar name was initially tacked onto IBM hard drives, however after some faults with the 75GXP model hard drive things went downhill for IBM and eventually Hitachi took over. Oddly enough, even though the Deskstar name has become somewhat of a second-rate name they still decided to use it for their Desktop HD product line.
The drive we look at today is the Hitachi Deskstar 7K400, which is a 400GB hard drive that carries five 80GB platters with 8mb of cache. Technically this drive is no different than its predecessor the Deskstar 7K250, with the only difference being that the 7K400 has two additional platters. Unfortunately unlike the Seagate drive, the Hitachi 7K400 doesn't include the NCQ technology.
It should also be noted that recently Hitachi has announced their Deskstar 7K500, which is a 500GB Serial ATA II (3.0Gb/s) drive, with 16mb of cache. They also have a new Serial ATA II version of their 7K250 labeled the T7K250.
