Seek 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:
• 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 5000 measurements of seeks between random
tracks, less overhead.

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks, regardless of
mode (such as track-to-track and average), are expected to meet the noted values. However, due to the manner in which
Note
these drives are formatted, benchmark tests that include command overhead or measure logical seeks may produce
results that vary from these specifications.
