Western Digital subsidiary HGST said on Tuesday that it has shipped its new MegaScale DC 4000.B, a 3.5 inch SATA 3 (6 Gb/s) hard drive with a 4 TB capacity. The company said this drive 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," said Brendan Collins, vice president of product marketing, HGST. "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."
The MegaScale is one of the company's "CoolSpin" drives, which is an optimization of the motor speed to provide an ideal balance of performance, power utilization and acoustics. Thanks to this technology, the company claims that this drive uses up to 45 percent less operating power and 29 percent reduced idle power when compared to current 4 TB 7,200 RPM drives. That means a possible significant cost savings for data center customers.
The company claims that the MegaScale DC 4000.B 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 supposedly consume less than one watt per drive so that archival applications remain online and response-ready, at the "most eco-friendly" power levels.
The drive's tech specs include a data buffer of 64 MB, a maximum interface transfer rate of 600 MB/sec, a typical sustained transfer rate of 110 to 140 MB/sec, and a MTBF of 800,000. The 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. The drive is meant for low application workloads that operate within 180 TB per year, the company claims.
"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," reads the company's press release. "The 4 TB MegaScale DC 4000.B offers 33 percent more capacity than 3 TB HDDs and supports 512e Advanced Format for custom data center environments."
The 4TB MegaScale DC 4000.B is currently shipping and comes with a three-year limited warranty.
