HARD DRIVE MAKER Western Digital has released 2.5TB and 3TB hard drives aimed at storing video.
Western Digital, which recently purchased rival storage vendor Hitachi Global Storage Technologies, announced that its AV-GP series of hard disk drives now come in 2.5TB and 3TB models. Both drives have the firm's Silkstream technology, which Western Digital claims can capture 12 simultaneous high definition video streams.
As its AV-GP drives are intended to run 24x7, Western Digital quotes a 1,000,000 hour mean time between failures and not the usual 300,000 load/unload cycles. The firm also spins the platters at somewhere between 5,200 and 5,700 RPM. However unlike its widely respected Black edition hard drives, the AV-GP units come with a three year warranty.
Western Digital is pitching its AV-GP drives for use in personal video recorders (PVR) and surveillance systems. For consumers it's debatable as to what advantage they will see by using the firm's specialised drives over its standard units in single drive PVRs.
Western Digital promotes its Silksteam firmware as being the major difference that, the firm claims, supports the SATA streaming command set, but its likely users will only see major gains on streaming servers used in surveillance applications.
Western Digital's 2.5TB AV-GP drive should be available for around £85 while the 3TB unit should set you back about £110. µ
