2TB models in 6Gb operation
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 5.). 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.
