7.3 Power dissipation 300 GB models in 3 Gbit operation Typical power dissipation under idle conditions in 3Gb operation is 3.79 watts (12.93 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 19). 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. Figure 19. 300GB (at 3 Gbit) DC current and power vs. input/output operations per second Savvio 10K.3 SAS Product Manual, Rev. J 27

Power dissipation
300 GB models in 3 Gbit operation
Typical power dissipation under idle conditions in 3Gb operation is 3.79 watts (12.93 BTUs per hour).
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure
19). 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.
