HGST Ultrastar 7K4000 is the world's first 4TB 7200 RPM Power Control Up to 4 terabytes2 of capacity hard drive with a million hours MTBF specification Operating at 7200 RPM, Ultrastar 7K4000 offers better SATA 6Gb/s and SAS 6Gb/s models for configuration and backed by a full 5-year warranty. Ultrastar 7K4000 . overall performance than slower RPM capacity-oriented represents the sixth-generation HGST 5-platter design, flexibility drives, and does so at impressively low power-consumption which has been field proven by top server and storage rates.

2 The Ultrastar 7K4000 can help data centers achieve Advanced Format* SATA with 512-byte OEMs and Internet giants. Engineered for the highest lower AC power and HVAC requirements. With five emulation (512e)* quality, the Ultrastar 7K4000 is put through grueling design Advanced Power Management modes, the 7K4000 achieves tests during development and must pass stringent ongoing Dual Stage Actuator (DSA) and Enhanced Rotational a 59% reduction in watts during low RPM idle mode, and reliability testing during manufacturing.

3 Ultrastar 7K4000 . Vibration Safeguard (RVS) for robust performance in uses less than 2W during standby/sleep modes, freeing up delivers by reducing downtime, eliminating service calls precious headroom for growing enterprise needs. multi-drive environments and minimizing TCO. 24x7 accessibility for enterprise-class, capacity- optimized applications Increasing Capacity Density by Innovating for a More 5-year limited warranty One Third Sustainable Environment The Ultrastar 7K4000 , with its halogen-free design and To deal with the explosive petabyte (PB) growth, data centers power-efficient operation, minimizes environmental impact require large amounts of efficient storage.

4 Reducing W/GB. Applications/Environments without expanding floor space is vital to lowering operating costs. To meet these demands, Ultrastar 7K4000 delivers 33%. in the areas of product design, manufacturing, operation and disposal. Cloud storage more capacity in the same footprint at 24% lower W/GB than Massive Scale Out (MSO) its predecessor, Ultrastar 7K3000. Now you can get in the footprint of a standard 19-inch enterprise storage rack by Data warehousing & mining stacking ten 4U, 60-bay enclosures. Ultrastar 7K4000 dual HGST Quality and Service Disk-to-disk backup & archiving port SAS is available in traditional 512, 520 and 528 byte sector HGST's Ultrastar 7K4000 extends the company's long- size.

5 Ultrastar 7K4000 SATA is an Advanced Format* drive, standing tradition of performance and capacity leadership. RAID arrays using 4096-byte sector size to provide enormous capacity The proven drive design enables high reliability and availability Network Attached Storage (NAS) earlier than otherwise possible for environments optimized to customer data. Ultrastar quality, performance and world for this technology. Advanced Format drives are backwards class technical support and service provides customers with a compatible with legacy 512-byte sector size by offering built-in lower total cost of ownership over previous generations.
