The Competition
The Raptor is definitely a very unique drive for the reasons we've mentioned previously, it competes with both IDE and SCSI drives. When we set out to evaluate the performance of the Raptor we put together a list of competitors from both the IDE and SCSI worlds; what we ended up with is best expressed in the following table:

From the ATA and Serial ATA worlds we have every single 8MB buffer drive available today; so independent of the WD Raptor's performance, we're able to provide you with a comparison of the best of the best when it comes to IDE drives today.
On the SCSI side, we have the two highest performing 10,000RPM drives - the Maxtor Atlas 10K IV and the Seagate Cheetah 10K.6. Pitting the Raptor against 15,000RPM SCSI drives wouldn't provide for a fair comparison so we left drives like the Seagate X15 out of the roundup.
