Hitachi Deskstar 7K1000.D review

Price when reviewed

Hitachi has been swallowed up by Western Digital, but part of the agreement means it’ll have to remain an independent firm for at least two years. That means some healthy competition in the hard disk market and, crucially, that drives like the Deskstar 7K1000.D will keep appearing on the market.

Hitachi Deskstar 7K1000.D review

Our 1TB sample has a SATA 6Gbit/sec connection, runs at 7,200rpm, and includes 32MB of cache – half the amount used by the majority of high-end hard disks.

That didn’t seem to matter in our tests, though. A large file write speed of 333.2MB/sec is the best we’ve seen from any hard disk, with the Samsung Spinpoint F3 scoring a result of 302.5MB/sec. A large file read speed of 161.6MB/sec is excellent – only one other drive, Seagate’s Barracuda XT, has run through that benchmark faster.

In our small file tests, the Hitachi’s write score of 158.4MB/sec was middling – the Samsung’s 165.2MB/sec score is the best we’ve seen – but a read pace of 30.6MB/sec was faster than every other drive we’ve tested.

Our final benchmark, the third-party AS SSD tool, also saw the Hitachi return good results. The Hitachi’s 186.6MB/sec sequential write speed is the best we’ve seen, outpacing the Samsung by more than 40MB/sec. Its 187.6MB/sec score in the sequential read benchmark is, again, the quickest we’ve recorded.

You might expect to pay a little more to net this kind of performance, but fortunately that’s not the case: for 1TB of super-fast hard disk storage you’ll have to cough up £65, which works out at 6.9p per gigabyte. That’s comparable with the Samsung, which costs £62.

In short, the Hitachi Deskstar 7K1000.D is a superb all-rounder. Let’s just hope that, once that two year period is up, Western Digital lets Hitachi keep making drives like this.
