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 rotate1/2 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.
