Drive Specifications

2.7Start/stop times

Start/stop times for alll models are listed below.

Start/stop times @ 25°C

2000 and 1500GB models

 

 

Power-on to ready (max)

<17.0s

 

 

Standby to ready (max)

<17.0s

 

 

Ready to spindle stop (max)

10.0s

 

 

Time-to-ready may be longer than normal if the drive power is removed without going through normal OS power- down procedures.

2.8Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. (Refer to Figure 3 ).

2.8.1 Power consumption

Power requirements for the drives are listed in Table 2 on page 15. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V 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.

• Read/write power and current

Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay, then a 16-sector read followed by a 32-ms delay.

• Operating power and current

Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.

• Standby mode

During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are in power-down mode.
