2.6 Physical characteristics 2.7 Seek time
Seek measurements are taken with nomin al po wer a t 25 °C amb ient t empe ratur e. All ti mes a re m easu red 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 5,000 measurements of seeks between
random tracks, less overhead.
Note. These drives are designed to consistently meet t he se ek t im es repr esente d i n this manu al . 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 these drives are formatted, benchmark tests that
include command overhead or measure logical seeks may produce results that vary from these
specifications.
