The drive is known as the Deskstar
7K1000.B and the main feature is the use of three platters that each store
374GB of data. With the drive only needing three platters, the idle power
consumption of the drive is reduced up to 43% over Hitachi’s first generation
1TB HDD. The 7K1000.B also offers users the option of bulk data encryption
(BDE) for the entire contents of the drive.
The 7K1000.B makes use of perpendicular magnetic recording and the drive’s BDE
option uses AES encryption certified by the National Institute of Standards and
Technology to deliver the strongest commercially available levels of security
Power requirement for the 7K1000.B is 5.2W at idle and the drive uses a 16MB
cache. The drive has a maximum media transfer rate of 1388 Mbits/s. The
Hitachi 7K1000.B will ship worldwide in July at an undisclosed price.
For enterprise users needing a high mean time between failure (MTBF), a
DeskstarE7K1000 drive is also being introduced that has up to a 32MB buffer and
a 1.2 million hour MTBF featuring the same low power requirements and optional
generation Hitachi 1TB HDD was released in January 2007.
