Power dissipation
Typical power dissipation under idle conditions is 10.49 watts (35.79 BTUs per hour) during 1 Gbit operation.
Typical power dissipation under idle conditions is 10.75 watts (36.68 BTUs per hour) during 2 Gbit operation.
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure
2). 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.
