300GB models in 6 Gbit operation Typical power dissipation under idle conditions in 6Gb operation is 3.82 watts (13.03 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 20. 300GB (at 6 Gbit) DC current and power vs. input/output operations per second 28 Savvio 10K.3 SAS Product Manual, Rev. J

300GB models in 6 Gbit operation
Typical power dissipation under idle conditions in 6Gb operation is 3.82 watts (13.03 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.
