The Western Digital Raptor (often marketed as WD Raptor, 2,5" models known as VelociRaptor) was a series of high performance hard disk drives produced by Western Digital first marketed in 2003. The drive occupies a niche in the enthusiast, workstation and small-server market. Traditionally, the majority of servers used hard drives featuring a SCSI interface because of their advantages in both performance and reliability over consumer-level ATA drives. Despite having been in production since early 2003, there was no direct competition in the same market for many years.
