Delivering Industry-Leading Quality & Reliability HGST Ultrastar 7K4000 is the world's first 4TB 7200 RPM hard drive with a 2.0 million hours MTBF

Specification & 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 & storage OEMs & Internet giants. Engineered for the highest quality, the Ultrastar 7K4000 is put through grueling design tests during development & must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime, eliminating service calls & minimizing TCO. 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 & Granular Power Control Operating at 7200 RPM, Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives, & does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power & HVAC requirements. With five Advanced Power Management modes, the 7K4000 achieves a 59% reduction in watts during low RPM idle mode, & 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 & power-efficient operation, qualifies for the HGST Eco Trac classification, which identifies products that minimize environmental impact in the areas of product design, manufacturing, operation & disposal. HGST Quality & Service Ultrastar 7K4000 extends the company's longstanding tradition of performance & capacity leadership. The proven drive design enables high reliability & availability to customer data. Ultrastar quality, performance & world class technical support & service provides customers with a lower total cost of ownership over previous generations. HGST drives are backed by an array of technical support & services, which may include customer & integration assistance. HGST is dedicated to providing a complete portfolio of HDD/SSD solutions to satisfy today's monumental computing needs. Features 2.0 million hours MTBF Up to 4 terabytes of capacity Advanced Format 512 byte emulation (512e) 6 Gb/s SATA interface Dual Stage Actuator (DSA) Enhanced Rotational Vibration Safeguard (RVS) 24x 7 accessibility for enterprise-class, capacity-optimized applications 5-year limited manufacturer warranty Applications / Environments

World’s first helium HDD – Patented Helio Seal™ technology enables this new building block for future growth Industry’s first 6TB HDD – Innovative 7 Stac™ disk design enables the world’s highest capacity TCOptimized™ platform – Delivers higher capacity, lower power, cooler & quieter operation in a standard 3.5-inch form factor HGST delivers the world’s first hermetically sealed, helium hard drive, the Ultrastar He 6 for massive scale-out environments. Why does helium make a difference? Helium has only one-seventh the density of air. Replacing air with helium inside a hard drive dramatically reduces the turbulence caused by the spinning disk, cuts power consumption & results in a lower temperature within the disk drive. The reduction in turbulence for the spinning disk allows HGST to offer a seven-disk design in a traditional 3.5-inch form factor. In addition to being the world’s first helium-filled hard drive, HGST Ultrastar He 6 is also the first hard drive in the industry to offer a 6-terabyte capacity. This design delivers a 50% capacity gain & still reduces the energy needed to run the drive by up to 23%. Highlights Highest capacity HDD on the market; 6TB, seven-disk design, providing the best TCO Lowest power consumption with best watts-per-TB
- 23% lower idle power per drive
- 49% better watts-per-TB Best density footprint in a standard 3.5-inch form factor
- 50% higher capacity Lighter weight than a standard five-disk 3.5-inch drive
- 50g lighter even with two more disks, offering 50% more capacity
- 38% lower weight-per-TB Applications/ Environments High-density data centers Massive scale-out data centers Containerized data centers Nearline storage applications Bulk storage Enterprise & data center applications where density & capacity are paramount
