Physical characteristics

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 5,000 measurements of seeks between

random tracks, less overhead.

*Measured in performance mode.

**Measured in quiet mode.

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 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.
