Hitachi Releases 2-TB, 7,200-rpm Enterprise-Class Drives
August 11, 2009 7:28 PM ET
Hitachi Global Storage Technologies on Tuesday unveiled the industry's first 2-TB hard drive with a spindle speed of 7,200 rpm, and aimed it squarely at enterprise applications requiring both performance and capacity.
The introduction of HGST's new Ultrastar A7K2000 comes just days after the company released its Deskstar 7K2000, a 2-TB, 7,200-rpm drive designed for high-performance, high-capacity desktop PC applications.
The new Ultrastar A7K2000 SATA drive is designed for rack-mounted, multidrive arrays for applications such as data warehousing, disk-to-disk backup, cloud computing, and massive scale-out storage implementations, said Mark Hall, senior product line manager for enterprise drives at HGST.
While both the new Ultrastar and Deskstar SATA drives feature the same capacity and spindle speed, they are different, Hall said.
The Deskstar 7K2000 is built using a five-platter design, with each offering 400 GB of capacity. The Ultrastar A7K2000 is a four-platter design, with each platter offering 500 GB of capacity.
The Enterprise-class Ultrastar A7K2000 also includes Hitachi's Rotational Vibration Safeguard (RVS) sensor technology, which helps increase performance in multidrive RAID arrays and rack-mounted systems by lessening the impact of one drive's vibration on other drives mounted next to it, Hall said.
The Ultrastar A7K2000 is also rated at 1.2 million hours mean time before failure (MTBF), has a better unrecoverable error rate, and comes with a five-year warranty. The Deskstar 7K2000 does not have an MTBF rating, and comes with a three-year warranty, Hall said.
Another big difference is the Ultrastar A7K2000's hardware encryption option, which encrypts data at line speed without a performance hit, Hall said.
Both drives are available. The Deskstar 7K2000 is currently shipping on an OEM basis via specific PC manufacturers, and will be available to the channel later this month. It is list-priced at $329. HGST is not discussing the list price for the Ultrastar A7K2000, Hall said.
