Seagate has announced the world’s first 3.5-inch hard drive to offer 1TB of storage capacity per disk platter, another first and should prove very useful for computer makers. The new Hard Drive is from the company’s GoFlex Desk product line-up and is dubbed the Barracuda XT, when all platters adds up there is a nice 3TB of storage available. It breaks the 1TB areal density barrier and is also available in the storage options of 2TB, 1.5TB and 1TB. Other than its 1TB per disk platter it also sets more records by being the industry’s highest areal density of 625 Gigabits per square inch. There has been no pricing information found on the Seagate Barracuda XT 3TB Hard Drive but it is expected to debut sometime this summer.
