ST32000444SS and ST32000445SS in 3Gb operation

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 8). 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.
