3 Gb/s SATA interface 300 MB/s burst data rate for faster data access

32 MB cache buffer Enhanced data transfer performance

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 enterprise and nearline applications
requiring high-capacity storage. 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.

1.0 TB, 750 and 500 GB | 7200 RPM
3 Gb/s SATA

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 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.

Intended for use in lower duty cycle environments in the enterprise storage hierarchy, such as RAID and nearline applications. This MTBF target
is based on a sample population and is estimated by statistical measurements and acceleration algorithms under nominal operating conditions.
MTBF ratings are not intended to predict an individual drive’s reliability. MTBF does not constitute a warranty.
