Western Digital (WD) has unveiled new 20TB Ultrastar DC HC560 and WD Gold hard drives for those looking for increased data density.
Both drives come in the standard 3.5-inch form factor and feature OptiNAND. This technology integrates iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disks, packing 20TB onto nine platters (2.2TB/platter). Both drives also make use of Energy-Assisted Magnetic Recording (EAMR), HelioSeal technology to minimize the air drag on the rotating platters, and a triple-stage actuator (TSA).
All this comes together to make a drive that has a projected MTBF rating of 2.5 million hours.
The Ultrastar DC HC560 is a disk aimed at hyperscale cloud, CSPs, enterprises, or those running big smart video surveillance systems or need high-capacity NAS drives.
No pricing was available at the time of writing for the 20TB Ultrastar DC HC560 .
The WD Gold are hard drives designed with enterprise-grade reliability — ten times that of a standard desktop drive — and is aimed at those with heavy-duty workloads.
The 20TB WD Gold retails for $679.99.
