Western Digital has just announced their new 12TB hard drive, once again taking the "we've got the biggest hard drive" crown again. Rumor has it Seagate is working on their 16TB drive that will be hitting markets next year but until then if you need more capacity in a single drive, Western Digital has you covered. TechRadar takes a closer look at the new capacity king.

Western Digital has announced that it’s now shipping the HGST-branded Ultrastar He12, a helium-based (‘HelioSeal’) 12TB hard disk.

This is a fourth-generation 3.5-inch helium hard drive which is built using PMR (perpendicular magnetic recording) technology and made for supreme reliability, which isn’t surprising seeing as it’s aimed at the enterprise arena – but it gives us a good flavour of what’s coming to the consumer world, too.

The disk boasts an impressive rated MTBF (mean time between failures) of 2.5 million hours.
