As petabyte (PB) growth continues to increase at a rapid pace corporate and cloud data centers are under extreme pressure to improve the efficiency of storage. To address this data center challenge HGST introduces Ultrastar® 7K6000 delivering up to 6TB of capacity and an industry-standard 3.5-inch hard drive for capacity-optimized enterprise applications. Ultrastar 7K6000 provides 50% more capacity and 33% better power efficiency in terms of Watts per terabyte (W/TB) than its predecessor Ultrastar 7K6000 also delivers greater storage efficiency through best-in-class performance achieving up to 3X higher write performance even at higher workloads thanks to HGST media cache architecture a disk-based caching technology which provides a large non-volatile cache on the disk. Media cache also allows for improved reliability and data integrity during unexpected power loss.
