Hitachi Deskstar T7K250 250GB 7200RPM SATA2 Hard Drive

Hitachi Deskstar T7K250 250GB 7200RPM SATA2 Hard DriveThe Hitachi Deskstar T7K250 is just a souped up version of the its little brother, the 7K250. Unlike the slower version this one only comes in 160GB and 250GB versions.

It’s faster speed comes from the fact that there are only two platters inside, each packed with 130GB of space instead of 90GB. This compactness allows quicker access to the information on the disk.

Features at a glance…

  • SATA2
  • 7200RPM
  • Faster data access than predecessor
  • 8MB buffer

As with other Hitachi drives it comes with SATA2. Although it still uses less bandwidth than SATA its still a nice thing to add in.

It doesn’t however support Native Command Queuing. NCQ speeds up data transfer by intelligently reordering reads and writes so as to minimize drive spin time. The lag in the disk spinning to the right spot accounts for much of the lag in hard drives.

There is an UltraATA/133 version of this drive that should deliver similar performance if you don’t need or want SATA.

In terms of performance this drive is slightly faster than the rest of the Hitachi drives.

Write and Read transfer rates are similar with both coming in at an average 52MB/s. Interface bandwidth gets a very high score of around 118MB/s.

A good performer, which should be fine for a few years because of its decent size.
