In the end, though, the fact that the Atlas 10K IV is a more expensive drive than the Cheetah 10K solidifies Seagate's win. Quite simply, the Cheetah 10K.6 is usually faster and almost $150 cheaper.

In most of our tests, both Maxtor and Seagate's 10K-RPM SCSI drives offer better performance than Western Digital's Serial ATA Raptor. Overall, the Raptor's performance is somewhere between more mainstream Serial ATA drives and the latest 10K-RPM SCSI drives. Not bad for the first product to mate 10K-RPM spindle speeds with Serial ATA technology.

At the end of the day, I'm going to give Seagate's Cheetah 10K.6 our Editor's Choice award for 10K SCSI drives. And, because it's such a unique drive and impressive performer, Western Digital's Raptor WD360GD also gets an Editor's Choice nod for Serial ATA.
