Another low-level benchmark which reproduces precise results and requires raw hard drives that is, drives without any file system or partitions. Seagate's Barracuda 7200.11 posted the best sequential transfer speeds¬we attribute this to better drive electronics and higher cache. The WD 320 GB AAKS (last year's winner), still holds its ground and delivers a performance as good as Seagate's new generation drives.

Seagate's Barracuda 7200.11 500 GB trumps in this test. Hitachi drives, especially the 1 TB does come really close to the winner, but looses out by a tiny margin. Though one would expect the WD Raptor to deliver a knockout performance, its 1.5 Gbps interface limits it. We expect the new VelociRaptor to put up a better show.
