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 contin-
ues 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 mixed-
drive environments.

In multi-drive environments, rotational vibration, which results from the vibration of neigh-
boring 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.
