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.
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.
Compatibility:
This drive is compatible with any server that accepts 3.5"x1" (LFF) SATA hard drives.
