Stratum use only the latest high performance, low power, hard drives from the leading manufacturers, Toshiba, Hitachi, Western Digital, Maxtor, IBM, Seagate and Conner.

BIOS limitations mean that some portables and desktops are unable to recognise the full capacity of the hard disk. Stratum's upgrades automatically include a BIOS extension to overcome this limitation.

Increasing storage demands made by the latest operating systems and application software make the need for larger and faster hard disks even greater.
