More Info

The 4TB HUS724040ALE640 UltraStar 7K4000 HDD from HGST is a hard drive designed to work in some of the most demanding environments. Utilize this drive in conjunction with a variety of other drives in cloud storage, massive scale out configurations, data warehousing and mining, RAID arrays and more. The 4TB storage capacity is sufficient for storing a variety of files including videos, photos, documents and more. Access data quickly and efficiently through the integrated SATA 6Gb/s interface supporting data transfer rates up to 600 MB/s along with a 64 MB data buffer ensuring a fast, efficient data flow.

Increasing Capacity Density by One Third
Lower operating costs without expanding floor space by reducing W/GB. To meet these demands, Ultrastar 7K4000 delivers 33% more capacity in the same footprint at 24% lower W/GB than its predecessor, Ultrastar 7K3000. Take advantage of 2.4PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U, 60-bay enclosures. Ultrastar 7K4000 dual port SAS is available in traditional 512, 520 and 528 byte sector size. Ultrastar 7K4000 SATA is an Advanced Format drive, using 4096-byte sector size to provide enhanced capacity. Advanced format drives are backwards compatible with legacy 512-byte sector size by offering built-in 512-byte emulation through the SATA interface.
Combining 7200RPM Performance and Granular Power Control
Operating at 7200RPM, Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives, and does so with lower 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 lower RPM idle mode, and uses less than 2W during standby/sleep modes, freeing up headroom.
Innovating for a More Sustainable Environment
The Ultrastar 7k4000, with its halogen-free design and power-efficient operation, qualifies for the HGST EcoTrac classification.
Enhanced Capacity
This 4TB HDD is a high capacity enterprise class drive available in a single platform.
Performance
With a 7200RPM rotational speed you benefit from increased performance for business critical applications along with the ability to maintain drive performance in high rotational vibration environments and multi-drive systems.
Reliability
Thermal Fly-height Control (TFC) with internal thermal sensors provides improved soft error rate detection for improved reliability and performance. The head load/unload feature protects disks during non-operation.
Security
Optional Bulk Data Encryption (SATA) and TCG Enterprise_A (SAS) encrypts drive data, providing security and easy redeployment.
