Western Digital Raptor WD740 SATA Hard Drive Review

Western Digital Raptor WD740 SATA Hard Drive Review - PCSTATS
Abstract: These are the first SATA drives we've seen that reach 10,000 RPM, and we're going to be testing them both singly and in a RAID stripe and mirror.

Benchmarks: HDTach

HD Tach V3.0.1.0 Source: TCD Labs Inc.

HD Tach is a physical performance hard drive test for Windows 95/98/ME and Windows NT/2000. In Windows 9X/ME it uses a special kernel mode VXD to get maximum accuracy by bypassing the file system. A similar mechanism is used in Windows NT/2000/XP. HD Tach reads from areas all over the hard drive and reports an average speed. It also logs the read speeds to a text file that you can load into a spreadsheet and graph to visually read the results of the test.

Transfer Graph: Single Raptor WD740

Transfer Graph: Dual Raptor WD740 RAID 0 Stripe

Transfer Graph: Dual Raptor WD740 RAID 1 Mirror

Like Sandra, HDTach does not see a performance difference between lone and Mirrored RAID 1 drive configuration. The lone WD740 Raptor averages a 65.1MB/s sustained data read, which is great. This benchmark is overly kind to striped RAID 0 sets as opposed to single drives, so I would not expect to see a real-life 50% performance advantage from striping. Still the numbers for the Western Digital drives continue to be impressive.
