| 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.
