Hitachi Deskstar 7K2000 HDS722020ALA330 - hard drive - 2 TB - SATA-300

The Deskstar 7K2000 hard drive delivers a colossal two terabytes of storage capacity and 7200 RPM performance in a standard 3.5-inch form factor. Now in its fourth-generation, the 7K2000 is based on a robust mechanical design that continues to set the industry standard for quality and reliability. Through a patented ramp load/unload design, data heads are moved to a ramp away from the disk where they rest during periods of inactivity. This greatly minimizes the risk of shock damage by eliminating direct contact between the heads and disks, reducing wear and heat while improving overall drive reliability and power efficiency. The Deskstar 7K2000 also incorporates Thermal Fly-Height Control (TFC) technology which uses an integrated heating element to precisely maintain a constant fly-height throughout read and write operations to enhance overall data integrity, drive performance and reliability.
