SATA II drives

The current SATA specification can support data transfer rates as high as 3.0 Gbit/sec per device. The main advantages over the older parallel ATA interface are faster data transfer, ability to remove or add devices while operating (hot swapping), thinner cables that let air cooling work more efficiently, and more reliable operation with tighter data integrity checks. While SATA drives are not as fast as Raptor or SCSI drives, they are excellent mass storage devices, with 1 SATA drive capable of holding 1TB of data.

Raptor drives

Western Digital first released the Raptor drive series in 2003. The Raptor drives are built with a 10,000rpm spindle speed offering a superior data transfer speed than conventional 7,200rpm drives thanks to lower rotational latency.
Instead of aiming the Raptor at the desktop market where prices were dropping through the floor, WD aimed the Raptor drives at the Enterprise market where generally the SCSI interface was favored. However, SCSI is traditionally very expensive. This makes the Raptor a very attractive choice.

SCSI drives

SCSI drives today are marketed exclusively for the server market, so you can be sure of getting a rugged drive engineered for continuous use. SCSI drives are available at spindle speeds of 10k RPM or 15k RPM.
