NOTES: Seek time is defined as the time from the receipt of a read, write or seek command until the actuator has repositioned and settled on the desired track with the drive operating at nominal DC input voltages and nominal operating temperature.

•Average seek time is determined by averaging the time to complete 1,000 seeks of random length.

•Average latency is the time required for the drive to rotate 1/2 of a revolution and on average is incurred after a seek completion prior to reading or writing user data.

•Startup time is the time elapsed between the supply voltages reaching operating range and the drive being ready to accept all commands.

•Actual rotational speed can be different a little.

•Performance specification is limited to the room temperature & normal voltage condition.
