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. Ultrastar 7K6000 provides 50% more capacity and 30% better power efficiency in terms of Watts per terabyte (W/TB) than its predecessor, Ultrastar 7K4000. The 7K6000 is designed for all traditional and rapidly growing scale-out storage applications, including object, block and file storage architectures, providing huge capacity, fast 7,200 RPM performance and economical $/TB acquisition cost. Ultrastar 7K6000 also delivers greater storage efficiency through high performance, achieving up to 3X higher random write performance, thanks to HGST media cache architecture, a diskbased caching technology, which provides a large non-volatile cache on the disk.

KEY FEATURES

Excellent random & sequential performance.
Reliable, field-proven, 7th generation 5-disk design.
128MB cache buffer improves response time and data management.
Instant Secure Erase (ISE) & Self-Encrypting Drive (SED) options.
