Hitachi Deskstar 7K500 Hard Drive

The Hitachi Deskstar 7K500 achieved sequential read and write speeds that were very similar to the Seagate but which were significantly slower than the Raptor. Of course the Raptor uses 2.5inch platters and has a rotational speed of 10,000rpm so you'd expect it to be fast, but even so the Hitachi wasn't as quick as we would expect for such a new design. It's very quiet in operation but it gets fairly hot and runs five to ten degrees hotter than a drive with fewer platters...
