HGST, a Western Digital company, has begun to ship its new MegaScale DC 4000.B hard disk drive (HDD). MegaScale DC 4000.B is HGST’s second-generatrion d 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.
“As a leading drive supplier to some of the world’s largest cloud data center providers, we understand the demanding storage requirements for low workload applications in these hyperscale environments. With the MegaScale DC 4000.B, we’re delivering massive capacity in a low-power, performance-optimized drive to help customers achieve superior capital savings, operational efficiencies and energy conservation in the data center,” said Brendan Collins, vice president of product marketing at HGST.
Not all hard drives are created equal. When selecting a SAS or SATA “enterprise capacity” HDD, it’s important to consider the application and the drive’s intended workload. Depending on the workload, each application requires specific HDDs to meet certain performance, capacity, availability, footprint and economic parameters. To ensure optimal efficiency, it’s critical that data center managers make informed decisions when selecting the right storage design with the right specifications for the right application workload.
Targeting 24/7 low workloads that operate within 180TB per year, 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 4TB MegaScale DC 4000.B offers 33% 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 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% less operating power and 29% reduced idle power when compared to current 4TB 7200rpm drives, which can mean significant cost savings for data center customers. 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 to help ensure that archival applications remain online and response-ready, at the most eco-friendly power levels.
MegaScale DC 4000.B hard drive also comes with optional bulk data encryption (BDE) with enhanced secure erase technology for added data security, and easy and safe hard drive redeployment.
In comparison, the HGST’s premium Ultrastar 7K4000 drives feature 7200rpm spindle speed and the industry’s highest MTBF specification at 2 million hours. Used in cloud and corporate data centers around the world, the Ultrastar 7K4000 family sets the benchmark for 7200rpm high-performance, high-quality and high-reliability 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.
“IT managers know that rapidly growing data in their data centers have a range of data access time and transfer speed requirements. HDD manufacturers are providing a variety of high capacity HDDs designed for various application workloads, including HGST's new MegaScale 4TB drive, to help IT managers realize total cost of ownership objectives over the life of the system,” said John Rydning, research vice president at IDC.
The 4TB MegaScale DC 4000.B is currently shipping and comes with a three-year limited warranty.
