Seagate has set a new commercial benchmark for HDD storage by breaking the 1 TB areal density barrier. The company has announced it will bring the world's first 3.5-inch hard drive with 1TB of storage capacity per disk platter to market in its GoFlex Desk product line, with the 3 TB Barracuda XT desktop hard drive (3 x 1 TB platters) expected to hit shelves in mid-2011.

The 1 TB platter drive has an areal density of 625 Gigabits per square inch, up from 488 Gigabits per square inch on Seagate's current drives.

Samsung, which recently announced a far-reaching strategic alignment with Seagate, showed a 1TB per platter drive at CeBIT 2011.

The new Seagate external hard drives will also be available in 2TB, 1.5TB and 1TB capacities – no pricing details or additional tech specs have been released as yet.

Looks like there's still life left in the platter.
