The 3.5” drive has reached 2TB with 2.5TB on the horizon the 2.5” HDD has struggled to math its big brothers ever increasing size. However Toshiba is releasing the MK6465GSX, the first 640GB 2.5” drive.

The dual “plattered” hard drive also comes in 160GB, 250GB, 320GB, 500GB capacities. However it only spins at 5,400RPM therefore its not the fastest of hard drives.

Toshiba have said they will be released later this month as the OEMs get shipped out to customers. The drive will also be used in a new range of Toshiba external drives. These will come in Liquid Blue, Vivid White, Rocket Red and Komodo Green colours, and the 640GB model will set you back around £110
