1.5 Seek time

The measurements are taken with nominal power at 25°C ambient
temperature. All times are measured using drive diagnostics. The spec-
ifications in the table below are defined as follows:
•
Track-to-track seek time is an average of all possible single-track
seeks in both directions.
•
Average seek time is a true statistical random average of at least 5,000
measurements of seeks between random tracks, less overhead.
•
Full-stroke seek time is one-half the time needed to seek from the first
data cylinder to the maximum data cylinder and back to the first data
cylinder. The full-stroke typical value is determined by averaging 100
full-stroke seeks in both directions.
