Hitachi Global Storage Technologies has quietly started to ship its hard disk drive with 4TB capacity with 7200rpm spindle speed. The new Deskstar 7K4000 hard drive weds extreme capacity with high performance and will likely become popular among enthusiasts this year.
The latest Hitachi Deskstar 7K4000 drive (HDS724040ALE640) boasts 4TB capacity and uses five previous-generation 800GB platters with 446Gb/square inch areal density, Serial ATA-600 interface, 64MB cache as well as 7200rpm spindle speed. The new hard disk drives use advanced 4K format.
It is unknown why Hitachi decided to utilize give previous-generation 800GB platters and not modern 1TB platters, but looks like the company was not sure that the latest platters would enable high-enough reliability. The Deskstar 5K4000 drive with 5400rpm spindle speed also sports five 800GB platters instead of 1TB discs.
Hitachi GST’s Deskstar 7K4000 HDD is currently available in Japan for ¥28800 ($377), a rather whopping drive even for a premium hard disk drive. As the situation with availability of HDDs will improve throughout this year, pricing of even the most advanced hard drives will get lower.
