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.
∗
Spin up 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.
