1.5 Seek time
All performance measurements are taken using a 25-MHz 486 AT
computer (or faster) with an 8.3-MHz I/O bus. The measurements are
taken using nominal power at sea level and at 25°C ambient temperature.
The specifications in the table on page 4 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.
