2.7 Seek time

Seek measuremen ts are taken with nom inal power at 25°C ambien t temper ­ature. All times are measured using drive diagnostics. The specifications in
the table below are defined as follows:

• Track-to-trac k seek time is an average of all pos sible si ngle-track s eeks 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.

Average

Average latency: 4.16 4.16

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 specifications.

2.8 Start/stop times

Power-on to Ready (sec) 10 (max)
Standby to Ready (sec) 10 (max)
Ready to spindle stop (sec) 20 (max)

2.9 Power specifications

The drive receives DC power (+5V or +12V) through a four-pin standard drive
power connector.
