Performance – Up to 3 times faster random write performance and 25% faster sequential write performance compared to the 7K4000. 12 Gb/s SAS and 6 Gb/s SATA – 12 Gb/s SAS for high-performance data centers; compatible with 6 Gb/s SAS.

As petabyte (PB) growth continues at a rapid pace, enterprise and cloud data centers are under extreme pressure to improve data storage efficiency. To address this challenge for data centers, HGST introduces the Ultrastar 7K6000 model, a standard 3.5-inch hard drive with up to 6 TB capacity for capacity-optimized enterprise applications. The Ultrastar 7K6000 offers 50% more capacity and 33% better energy efficiency in terms of watts per terabyte (W/TB) compared to its predecessor. The Ultrastar 7K6000 also provides greater storage efficiency through class-leading performance, delivering up to 3 times higher write throughput, even under heavier workloads, thanks to HGST's media cache architecture. This is a disk-based caching technology that provides a large non-volatile cache memory on the hard drive. Media cache also enables improved reliability and data integrity during unexpected power outages.
