Barracuda ES.2 FC Product Manual, Rev. B

6.3

Power dissipation

Typical power dissipation under idle conditions in 4 Gbit operation is 9.16 watts (31.26 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 your 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.
