2.7 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications below are defined as follows: � Track-to-track seek time is an average of all possible single-track seeks in both directions. � Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. Typical seek times (msec)* Read Write Track-to-track 1.0 1.5 Average 11.0 13.0

2.9 Power specifications The drive receives DC power (+5V) through the interface connector. 2.9.1 Power consumption Power requirements for the drives are listed in the table on page 12. Typical power measurements are based on an average of drives tested, under nominal conditions, 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. � Seek mode During seek mode, the read/write actuator arm moves

2.9.1.1 Typical current profile Figure 4. Typical 5V startup and operation current profile 2.9.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line. Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz. Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current. 2.9.3 Volt
