2.6 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 ran-

dom tracks, less overhead.

2TB model

1TB and 500GB model 250GB models

Typical seek times (msec)* Read Write Read Write Read Write

Track-to-track <0.5 <1.5 <0.5 <1.5 <1.0 <1.2

Average <8.5 <9.5 <8.5 <9.5 <8.5 <9.0

*Measured in Seek 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 val-

ues. 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.

2.7 Start/stop times

2TB model 1TB and 500GB models 250GB models

Power-on to Ready (max) <17s <10s <8s

Ready to spindle stop (max) 10s 12s 12s

Note. Start/stop measurements are taken with nominal power at 25°C ambient temperature.
