Power dissipation
3TB models 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 
2). 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.
