1.5 Seek time
All seek time measurements are taken under nominal conditions of
temperature and voltage with the drive mounted horizontally. In the
following table:
•
Track-to-track
seek time is the average of all possible single-track
seeks in both directions.
•
Average/typical
seek time is a true statistical random average of at
least 5,000 measurements of seeks in both directions between ran-
dom cylinders, less overhead.
•
Full-stroke
seek time is one-half the time needed to seek from logical
block address zero (LBA 0) to the maximum LBA and back to LBA 0.

Note.
Host overhead varies between systems and cannot be specified.
Drive internal overhead is measured by issuing a no-motion
seek. Drive overhead is typically less than 1.0 msec.

6. All possible one- track seeks are divided into the time required to perform these seeks.
Only the mechanism time is used; interface overhead is excluded.
7. All possible seeks are divided into the time required to perform these seeks. Only the
mechanism time is used; interface overhead is excluded.
8. The average of 1,000 full-stroke seeks is used in this computation. Only the mechanism
time is used; interface overhead is excluded.
