Hitachi Global Storage Technologies, a wholly-owned subsidiary of Western Digital, has unveiled the industry's first, and yet the only, enterprise-class hard disk drive (HDD) with 4TB capacity. The new Ultrastar 7K4000 hard drive combines leading-edge capacity, high performance, high reliability and low power consumption.
Hitachi Ultrastar 7K4000 family of 3.5" hard disk drives are available in 2TB, 3TB and 4TB capacities and are based on up to five modern platters with 446Gb/inch2 (691Mb/mm2) areal density. The drives feature 7200rpm spindle speed, 64MB cache buffer, Serial ATA 6Gb/s interface and so on. Hitachi declares 171MB/s sustained transfer rate, 8ms seek time, 11.4W average read/write power consumption and so on. The Ultrastar 7K4000 hard drives use 4KB/512e advanced format.
“We are humbled by the fact that our enterprise customers continue to appreciate and value our broad portfolio of enterprise HDDs and SDDs, which gives them multiple choices to satisfy a wide range of tiered storage requirements in the enterprise. With our new advanced format Ultrastar 7K4000 drives, we are providing enormous capacity earlier than otherwise possible for environments optimized for this technology, while delivering yet another offering that takes advantage of the Ultrastar family’s long-standing tradition of delivering high-reliability and low power for high-density cloud and big data applications,” said Brendan Collins, vice president of product marketing at HGST.
The new Ultrastar 7K4000 family addresses enterprise datacenter needs by offering high reliability and a low total cost of ownership (TCO). The 4TB Ultrastar 7K4000 drive delivers 33% more capacity in the same 3.5" footprint at 24% lower watts/GB than its predecessor, the 3TB Ultrastar 7K3000 drive. Now IT managers can get 2.4 PBs in the footprint of a standard 19-inch storage rack by stacking ten 4U, 60-bay enclosures. The Ultrastar 7K4000 family can also help datacenters achieve lower AC power and HVAC requirements. With five Advanced Power Management modes, the Ultrastar 7K4000 achieves a 59% reduction in watts from peak usage during low RPM idle mode, and uses less than 1W during standby/sleep modes, freeing up precious headroom for growing datacenter needs.
The Ultrastar 7K4000 family is set to continue this standard with a five-year limited warranty and a 2.0 million hours mean time before failure (MTBF) specification, resulting in a 40% lower annualized failure rate (AFR) than enterprise drives rated at 1.2 million hours MTBF.
The new Ultrastar 7K4000 family is now shipping in limited quantities. Customer samples are now available.
