Hitachi Deskstar 7K3000 3TB HDD review

Hi-cap, hi-speed - SATA 6Gbps for the win?

TODO alt text

With its SATA 6Gbps interface and 7,200rpm spindle speed the Hitachi Deskstar 7K3000 completely blitzes the Western Digital Caviar Green with its variable spin speed and 3Gbps interface, in the burst speed test and the average read test.

With both drives using a 64MB cache thought the random access times are almost identical.
