Claim 10:
11. A storage device comprising a drive arm having at least two read-write heads capable of accessing data synchronously, the storage device comprising:
at least one hard disk, wherein each hard disk is divided into at least two regions;
a drive arm, having at least two read-write heads, wherein each read-write head reads and writes data in a corresponding region of the at least two regions; and
a control unit, separating first data to be written into a plurality of write-data, wherein each write-data corresponds to a different read-write head of the at least two read-write heads for writing said first data synchronously, wherein the storage device has a configuration setting switch to change speeds of accessing data in one of the following conditions: 8× speed be changed to 4× speed with four read-write heads accessing data synchronously for a hard disk, 2 single-side hard disks with four read-write heads accessing data synchronously; 6× speed be changed to 3× with three read-write heads accessing data synchronously, and 2× speed with two read-write heads accessing data synchronously for a hard disk.
