Today WD has launched a new line of high performance desktop drives dubbed the VelociRaptor, and the product finally scales in capacity as well. The new SATA-based VelociRaptor weighs in at 300GB with the same 10K RPM spindle speed, but with one other major difference — it's based on 2.5" technology. Its smaller two platter, four head design affords the VelociRaptor random access and data transfer rates significantly faster than competing desktop SATA offerings. Areal density per platter has increased significantly as well, which contributes to solid performance gains versus the legacy WD Raptor series."
