WD1500AD Raptor X-Tends Performance Lead

Data Transfer Diagram

The new Raptor reaches a maximum transfer performance rate of more than 80 MB/s when the drive is empty; this is when the drive usually uses the outer area of the rotating platters where the absolute rotation speed is highest. The more capacity you utilize, the more the transfer rate is going to decrease; this is normal for all drives. The minimum transfer speed, however, is even more impressive than the maximum number. The Raptor-X does not fall below 55 MB/s, which some 7,200 RPM drives cannot even provide as a maximum.
