HGST Ships MegaScale DC Hard Drive For Low-Workload Applications

HGST, a Western Digital company, is shipping its new MegaScale DC 4000.B, a 3.5-inch, 4TB, 6 Gb/s SATA hard disk drive. The company's second-generation MegaScale drive has been optimized to meet the growth of infrequently accessed data, while balancing the mix of power, capacity, performance and reliability.

As part of a tiered storage strategy, the MegaScale DC 4000.B is designed for low-workload applications such as bulk storage for unstructured or big data, disk-to-disk backup, online archives, or long-term data retention where cost-per-GB, watt-per-GB and GB-per-square foot are critical parameters.

The MegaScale DC 4000.B HDD with CoolSpin has been optimized for 24/7 low-workload environments that operate within 180TB per year. These environments are characterized by being low-cost, high density and having moderate performance, and must be able to scale efficiently and deploy vast amounts of storage.

In comparison, the HGST's premium Ultrastar 7K4000 drives feature 7,200 RPM performance and a MTBF specification at 2 million hours. Used in cloud and corporate data centers around the world, the Ultrastar 7K4000 family sets the benchmark for 7,200 RPM high-performance in workloads that operate within 550TB/year. The drives are specifically designed for 24x7 capacity-optimized enterprise applications such as RAID, storage arrays, cloud storage, data warehousing, video-on-demand, disk-to-disk backup, and massive scale-out storage implementations where performance, reliability and storage density are critical.

The MegaScale DC 4000.B is rated at 800K MTBF, and offers specifications of 1 in 1014 non-recoverable bit error rate and 300K load/unload cycles. The MegaScale DC 4000.B features a Dual Stage Actuator (DSA) and Enhanced Rotational Vibration Safeguard (RVS) technology for full performance, better stability and more reliability in rack-mount drive bays and servers. The new hard disk offers 33 percent more capacity than 3TB HDDs and supports 512e Advanced Format for custom data center environments.

The 4TB MegaScale DC 4000.B also features HGST?s innovative CoolSpin technology that delivers "optimized" performance with low power for data centers looking to reduce their environmental impact and improve energy efficiency in terms of power usage, cooling and storage density footprint. Utilizing HGST?s CoolSpin technology, the drive uses up to 45 percent less operating power and 29 percent reduced idle power when compared to current 4TB 7,200 RPM drives, which can mean significant cost savings for data centers. The MegaScale DC 4000.B also offers five levels of Advanced Power Management around power consumption including: normal idle, unload idle, low RPM idle, standby, and sleep. The standby and sleep modes consume less than one watt per drive.

MegaScale DC 4000.B hard drive also comes with optional bulk data encryption (BDE) with secure erase technology.

The 4TB MegaScale DC 4000.B is currently shipping and comes with a three-year limited warranty.
