HGST 0A35770-RFB 500GB Hard Drive Sata 7200 0A35770-RFB

World�s first terabyte hard drive for the enterprise � Ideal for lower duty cycle storage in enterprise environments.

Record capacity, enterprise-class reliability
The Ultrastar- A7K1000 delivers up to one terabyte of storage capacity in a standard 3.5-inch form factor, filling a vital need for high-density storage in the enterprise. As the third generation design, based on the popular Deskstar- E7K500, the Ultrastar A7K1000 continues to set the standard in enterprise-class reliability and performance for lower duty cycle enterprise applications. With a unique 5-platter design, Hitachi has relaxed the bit densities to achieve higher reliability. The Ultrastar A7K1000 is built using the industry�s most reliable perpendicular magnetic recording (PMR) recording heads and media.

Performance targeted for the enterprise
The Ultrastar A7K1000 features a 3 Gb/s SATA interface supporting key features in the Serial-ATA specification including Native Command Queuing (NCQ), staggered spin-up and hot-swap capability. The Ultrastar A7K1000 allows for configuration scalability and with the same physical connector as Serial Attached SCSI (SAS) drives, it�s ideal for use in mixeddrive environments.
In multi-drive environments, rotational vibration, which results from the vibration of neighboring drives in a system, can degrade hard drive performance. To aid in maintaining high performance, the Ultrastar A7K1000 incorporates enhanced Rotational Vibration Safeguard (RVS) technology providing up to 50% improvement over the previous generation against performance degradation, leading the industry.
Finally, the Ultrastar A7K1000 is targeted at 1.2 million hours MTBF and provides the industry�s most comprehensive 5-year warranty.
