Please refer to Table 2 for power dissipation numbers.
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.
