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

|
|
| Read/write power is measured with the heads on track, based on a | |||

|
| |
• | 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 |
