300GB models in 3Gb operation
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 4). Locate the typical I/O rate
for a drive in the 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.
