Typical power dissipation under idle conditions in 4Gb operation is 4.07 watts (13.90 BTUs per hour).
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure
5). 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.
