2.7 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 av erage of at least 5,000 measurements of seeks betwee n
random tracks, less overhead.
T ypic al see k times (mse c) Read Write
Track-to-track <1.0 <1.2
Average 8.5 9.5
Average latency: 4.16 4.16
Note. These drives are designed to consistently meet the seek times represented in this manual. Physical
seeks, regardle ss of mode ( such as track- to-track and average), are ex pected to meet or exceed
the noted values. However, due to the manne r in which these drives are formatted, benchma rk
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.
