1.Execution time measured from receipt of the FCP Command to the FCP Response.

2.Assumes no errors and no sector has been relocated.

3.Typical access times are measured under nominal conditions of temperature, voltage, and hor- izontal orientation as measured on a representative sample of drives.

4.Access time = controller overhead + average seek time.

Access to data = controller overhead + average seek time + latency time.
