Let's take a look at the first terabyte hard drive, the Deskstar 7K1000 from Hitachi Global Storage, and see just how it performs. For an impressive $399 ($0.39/gig), is it worth your bucks?
Hitachi is the first to market with a 1TB hard drive, using the company's
perpendicular recording technology. The technology is similar to Seagate's 750GB 7200.10. Perpendicular recording orients the tiny magnetic domains vertically, with one orientation representing binary zeros and the opposite representing binary 1's.
Even so, Hitachi needs five platters and ten heads to hit 1TB. Having that many heads can have an impact on issues like noise and power draw. For example, the 750GB version of the drive is rated at 30dB while seeking; the 1TB sibling generates 32dB.
We're pretty impressed with the overall performance of the Hitachi Deskstar 7K1000. However, as we pack more
data onto these compact digital devices, the thought of losing that data is a bit daunting.
