Table 3-4: Performance Specifications
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.
