Hitachi Deskstar E7K1000 1TB Enterprise Hard Disk
E is for Enterprise; several manufacturers add
features to their standard desktop drives to make them perform better in
tightly packed clusters and in high performance RAID arrays. Hitachi was first
to market with a 1TB drive nearly two years ago. The first 1TB drive required
five platters to achieve the milestone mark; because of this, the drives ran a
little on the… touch it with your finger and feel the pain, hot side. Areal
densities have increased over the two year life span of 1TB drives and now
Hitachi is able to deliver a 1TB drive in only three platters.
The new E7K1000 is more than just a refresh on their
desktop product. The new drive features 32MB of cache, up from 16MB. The
additional cache should help to decrease latency access times. The feature most
useful for the E7K1000’s target audience is the Rotational Vibration Safeguard
(RVS). RVS is a set of sensors located on the drive and when vibration is
detected the internal software adjusts the head’s position in relation to the
platters to compensate. @ Tweaktown
