Ultrastar™ A7K2000
3.5-Inch Enterprise 7200 RPM
Hard Disk Drives
The Ultrastar A7K2000 delivers up to 1TB of storage capacity in a standard 3.5 form factor, filling a vital need for high-density storage in the enterprise. With a unique 5-platter design, Hitachi has relaxed the bit densities to achieve higher reliability. The Ultrastar A7K2000 is built using the industry s most reliable perpendicular magnetic recording recording heads and media. The Ultrastar A7K2000 features a 3 Gb/s SATA interface supporting key features in the Serial-ATA specification including Native Command Queuing , staggered spin-up and hot-swap capability
