The 300GB VelociRaptor Internal SATA Hard Drive from Western Digital is a high-capacity internal drive designed for use in servers. The drive is housed in a 3.5" enterprise-class mounting frame, complete with an integrated heat sink. Even though the drive platter itself is 2.5", it is not suitable for installation in notebook computers.
Boasting a SATA interface, a large 16MB data buffer, and a rotation speed of 10,000 rpm, this drive is an excellent solution for adding storage capacity to your desktop workstation or server.
