    U10 Family Product Manual, Rev. A 1.5 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The spec- ifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions.

  • Page 16: Power Consumption

    1.7.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
