EE25.2 Series Product Manual, Rev. B
2.6 Physical characteristics
2.7 Seek time
Seek measurements are taken with nominal power. All times are measured using drive diagnostics. The spec-
ifications 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.
Note. 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 or exceed the
noted values. However, due to the manner in which these drives are formatted, benchmark tests that
include command overhead or measure logical seeks may produce results that vary from these speci-
fications.
