OWER DISSIPATION
1200 GB models in 3Gb operation
Typical power dissipation under idle conditions in 3Gb operation is 4.59 watts 15.66 BTUs per hour).
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 the system on the horizontal axis and read the corresp5 volt current, +12 volt current, and total watts
on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.

1200GB models in 6Gb operation
Typical power dissipation under idle conditions in 6Gb operation is 4.63 watts 15.78 BTUs per hour).
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 3). Locate the typical
I/O rate for a drive in the system on the horizontal axis and read the corresp5 volt current, +12 volt current, and total watts
on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.
