6.4 POWER DISSIPATION 800GB models in 6Gb operation Typical power dissipation under idle conditions in 6Gb operation is 4.38 watts 14.95 BTUs per hour). To obtain operating power for typical random write 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.

800GB models in 6Gb operation
Typical power dissipation under idle conditions in 6Gb operation is 4.38 watts 14.95 BTUs per hour).
To obtain operating power for typical random write 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.
