| Since the 1980's, smaller form factor drives
have grown in storage capacity. Today's 3.5 inch form factor
drives designed for the server market can store more than 146
Gbytes in a 1 inch height using 84 mm diameter disks rotating
at 10,000 RPM, desktop drives can store 250 Gbytes per drive
on 95 mm diameter disks rotating at 7200 RPM, 2.5 inch drives
designed for mobile, notebook computers (and some compact desktop
computers) can store 80 Gbytes on 65 mm disks rotating at power
efficient 4200 RPM, and a new form factor, 1 inch, the Hitachi
GST Microdrive can store 1 Gbyte today with a projection of
4 Gbytes in the near future. Microdrive is designed for such
consumer applications as digital cameras, personal communications
devices and hand held computers. Form factor evolution to smaller
sizes has been accomplished without loss of capacity and often
has resulted in higher performance and lower power dissipation.
