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 data center challenge, HGST introduces the Ultrastar® 7K6000 model, a standard 3.5-inch hard drive with up to 6TB capacity for capacity-optimized enterprise applications. Ultrastar 7K6000 offers 50% more capacity and 33% better power efficiency in terms of watts per terabyte (W/TB) than its predecessor. Ultrastar 7K6000 also offers greater memory efficiency through best-in-class performance that delivers up to 3x higher write throughput, even at heavier workloads, thanks to HGST’s media cache architecture. This is a disk-based caching technology that provides a large non-volatile cache on disk. Media cache also enables improved reliability and data integrity during an unexpected power failure. characteristics
