*During periods of drive idle, som e offline activity may occur, according to the S.M.A.R.T. specification, which may increase acoustic and

power to operational levels.

**Typical notebooks will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby modes

will not contribute to battery power consumption.

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 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 r andom average of at leas t 5,000 measurements of s eeks between
random tracks, less overhead.

Typical seek times (msec) Read Write

Track-to-track 1.5 2.0
Average 12.5 14.5
Full-stroke 22.0 24.0
Average latency 5.56 5.56

Note. These drives are designed to co nsistently meet the seek times r epresented in this manual. Physic al

seeks, regardless of mode (such as tr ack-to-track and average), a re expected to mee t or exceed th e
noted values. However, due to the manner in which thes e drives are formatt ed, benchmark tests tha t
include command overhead or measure logical seeks may produce results that vary from these speci­fications.
