Last week Western Digital Corporation announced the release of their 12TB helium drive, the first hard disk drive shipped of this capacity. The drive makes use of the well-known Perpendicular Magnetic Recording (PMR) method.

The drive is aimed at the enterprise storage market, spinning at 7200rpm using the 3.5” form factor, available using the SATA or SAS interface. The hard drive uses a low-power design, aimed at reducing the running costs, particularly when compared to the largest air filled drives, currently 8TB in size.

A higher capacity drive, of 14TB is planned for 2017, which uses Shingled Magnetic Recording (SMR) aimed at data archiving. SMR drives are used quite often by cloud service providers to provide high capacity archive storage of data which rarely needs to be updated.
