20GB in match.

Hitachi has found room 20GB for data on a hard disk in diameter 2.5".
By the end of next year Hitachi Global Storage is measured to offer on the market small hard disks in diameter 2.5" on which it is possible to write down up to 20GB data. The density of record on these devices as engineers of the company approve, reaches 4.5GB on square centimeter. Achieve it in Hitachi could due to use of so-called perpendicular technology of data recording on the carrier. Already in it the company will present year on the market "transit" models of small hard disks, but in these models the density of record will be approximately twice less specified above. For comparison, modern "microdrives" have capacity nearby 6GB, that is Hitachi promises significant jerk forward.
