6.4 Power dissipation ST9600204FC Typical power dissipation under idle conditions in 4Gb operation is 8.32 watts (28.40 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 3). 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 3. ST9600204FC DC current and power vs. input/output operations per second Savvio 10K.4 FC Product Manual, Rev. A 27

Power dissipation
ST9600204FC
Typical power dissipation under idle conditions in 4Gb operation is
8.32 watts (28.40 BTUs per hour).
To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure
3). 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.
