Capacity – Up to 6 TB of enterprise-class storage on HGST“s proven 7th generation 5-disk platform
Performance – Up to 3x faster random write performance and 25% faster sequential write performance compared to 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 data center challenge, HGST introduces the Ultrastar® 7K6000, 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 power efficiency in terms of watts per terabyte (W/TB) than its predecessor. The Ultrastar 7K6000 also delivers greater storage efficiency through best-in-class performance, delivering up to 3x the write throughput, even at higher workloads, thanks to HGST“s media cache architecture, a disk-based caching technology that provides a large non-volatile cache memory on the disk. Media caching also enables improved reliability and data integrity during an unexpected power outage.
