Huge capacity, highest 7200 RPM reliability, plus outstanding performance for desktop storage

HGST Deskstar 7K4000 HDS724040ALA640 (0F14681) 4TB hard drive delivers a colossal two terabytes of storage capacity and 7200 RPM, 64MB Cache, SATA 6.0Gb/s performance in a standard 3.5-inch form factor. The 7K4000 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 7K4000 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.
