6TB drives are not really new to the market -at least the enterprise market, but Seagate are looking to throw their hat into the ring later this year by releasing a 6TB drive. Joining Western Digital, who were the first manufacturer to have a standard 3.5" 6TB drive on the market (with a seven platter helium filled hard drive). The Seagate offering much like the Western Digital is expected to also be an enterprise class hard drive -so don't get too excited just yet.
“We are continuing to expand our offering of high capacity drives with our six-disk, 6TB drive shipping early next quarter,” said Steve Luczo, chairman and chief executive of Seagate.
No other information is currently available regarding the process in which Seagate is expecting to create this behemoth of a drive, but I expect that a similar use of inert gas will be used to replace the air in the casing, allowing for more platters to be fitted whilst retaining the standard size and form factor.
