PC Stats posted Western Digital RaptorX WD1500AHFD 150GB Clear Top SATA Hard Drive Review

If you want the highest performance Serial ATA hard drives available, there's only one manufacturer to turn to and that's Western Digital. Its enterprise class Raptor hard drives are a hit among computer enthusiasts. The Western Digital Raptor hard drive achieves its remarkable performance thanks to the high rotation speed of its platters. At 10,000 RPM the WD Raptor is definitely one of the fastest spinning Serial ATA desktop HDD on the market, on par with enterprise level SCSI counterparts. While 7200 RPM drives are improving in performance by increasing platter density and putting larger caches on the HDD, Western Digital uses a "brute force" type method in increasing performance. It's not be the most elegant way but hey it works very well. ;-)
