Hitachi 1TB Deskstar 7K1000

The Hitachi Deskstar 7K1000 is a solid performer, but about 30% slower than the Western Digital RE3 on sustained transfers across the drive. However, it was a top performer in Photoshop tests on the MacBook Pro, showing that the particular workload and hardware involved can lead to very different conclusions.

When seeking, it is noticeably louder than Seagate 1TB models, but on par with the Western Digital RE3. While I didn’t experience it, a reader reports that the Hitachi sometimes has the same noisy behavior after heavy access as the Westen Digital RE 3; see details there.
