Western Digital has just announced its largest capacity drive based on conventional magnetic recording - the Ultrastar DC HD530.

14TB drives are not new, HGST, a subsidiary of Western Digital, announced a 14TB drive last year. But that was based on shingled magnetic recording (SMR).

SMR differs by writing new tracks that partially overlaps with existing tracks. This allows SMR drives to achieve a higher storage density than traditional hard disk drives that use perpendicular magnetic recording (PMR).

The new 14TB Ultrastar DC530 was designed for enterprise use, and they rely on PMR. They are also helium-filled. Inside each drive is eight 1.75TB platters and they spin at 7,200pm. Additionally, they will be available with either SATA or SAS interfaces.

Sustained transfer rate is claimed to be in the region of 267MB/s and the drives will be back by 5-year long warranties.

The Western Digital Ultrastar DC530 is expected to be available here sometime in May. Prices have yet to be confirmed.
