Performance Characteristics
Seek Times (typical)*
•
Track to Track: 2.0 msec
•
Average (read/write): 9.0/9.5 msec**
•
Full Stroke: 18 msec
* The timing is measured from the time the last byte of the command descriptor block is
written to the time seek is initiated by the drive operating at nominal DC input
voltage and nominal operating temperature.
** The average seek time is determined by averaging the seek time for a minimum of
1000 seeks of random length over the surface of the disk.

Maximum: 20 seconds
* These numbers assume spin recovery is not invoked. If spin recovery is invoked, the
maximum could be 40 seconds. Briefly removing power can lead to spin recovery
being invoked.
