HGST Ultrastar 7K4000 3.5 -Inch Enterprise Hard Disk Drives
Highlights 2.0 million hours MTBF Up to 4 terabytes of capacity Advanced Format 512 byte emulation (512e) 6Gb/s SATA interface Dual Stage Actuator (DSA) Enhanced Rotational Vibration Safeguard (RVS) 24x7 accessibility for enterprise-class, capacity-optimized applications 5-year limited warranty Applications / Environments Cloud storage Massive Scale Out (MSO) Data warehousing & mining Disk-to-disk backup & archiving RAID arrays Network Attached Storage (NAS) Delivering Industry-Leading Quality and Reliability
HGST Ultrastar 7K4000 is the world's first 4TB 7200 RPM hard drive with a 2.0 million hours MTBF specification and backed by a full 5-year warranty. Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design, which has been field proven by top server and storage OEMs and Internet giants. Engineered for the highest quality, the Ultrastar 7K4000 is put through grueling design tests during development and must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime, eliminating service calls and minimizing TCO. 4TB, 3TB and 2TB
7200 RPM ^^ SATA 6Gb/s
Increasing Capacity Density by One Third
To deal with the explosive petabyte (PB) growth, data centers require large amounts of efficient storage. Reducing W/GB without expanding floor space is vital to lowering operating costs. To meet these demands, Ultrastar 7K4000 delivers 33% more capacity in the same footprint at 24% lower W/GB than its predecessor, Ultrastar 7K3000. Now you can get 2.4 PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U, 60-bay enclosures. Ultrastar 7K4000 is an Advanced Format drive, using 4096-byte sector size to provide enormous capacity earlier than otherwise possible for environments optimized for this technology.

Advanced Format drives are backwards compatible with legacy 512-byte sector size by offering built-in 512-byte emulation through the SATA interface. Combining 7200 RPM Performance and Granular Power Control
Operating at 7200 RPM, Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power and HVAC requirements. With five Advanced Power Management modes, the 7K4000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 1W during standby/sleep modes, freeing up precious headroom for growing enterprise needs. Innovation for a More Sustainable Environment
The Ultrastar 7K4000, with its halogen-free design and power-efficient operation, qualifies for the HGST EcoTrac classification, which identifies products that minimize environmental impact in the areas of product design, manufacturing, operation and disposal. HGST Quality and Service
Ultrastar 7K4000 extends the company's longstanding tradition of performance and capacity leadership. The proven drive design enables high reliability and availability to customer data.
