Like the previous generation WD Raptors that came before it, the 300GB WD Velociraptor shares the aforementioned 10K RPM spindle speed, and they have the same 16MB buffer, reliability ratings, and acoustic and environmental characteristics as well. The WD Velociraptor sports a completely new design, however, that offers significantly increased performance, in terms of access times, IOPS, and data transfer rates.
