The 10,000 RPM VelociRaptor hard drive is actually a 2.5″ hard drive enclosed in a 3.5″ form factor heat sink. The VelociRaptor 300 is a 300GB hard drive with a 3.0Gbps SATA interface, Western Digital says that the drive is capable of sustaining 120MB/s which is incredibly fast for a single hard drive.
AnandTech reports that the drive averages about 98.4MB/s. This difference in speed is mostly due to the fact that reading data from the outside of the platter won’t be as fast as reading data from the inside of the platter.
The drive will be priced at $300 which is a great deal considering how fast it is. The drive will surely make a dent in the enterprise market where fast drive speeds are a must and I would imagine that this drive would also do pretty well for media professionals capturing video to hard drives.
