2.5Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows:
•
•Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.
Typical seek times (msec) | Read | Write |
