Power dissipation

ST973401FC
Typical power dissipation under idle conditions in 1Gb operation is 6.6 watts (22.5 BTUs per hour).
Typical power dissipation under idle conditions in 2Gb operation is 6.9 watts (23.7 BTUs per hour)
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure
6). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5
volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by
3.4123.
