400GB standard 1.8" models in 6Gb operation
(Models ST400FM0023, ST400FM0043, ST400FM0063, ST400FM0083)
Typical power dissipation under idle conditions in 6Gb operation is 3.08 watts (10.51 BTUs per hour).
To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 12). Locate the
typical I/O rate for a drive in the system on the horizontal axis and read the corresponding +3.3 volt current, +5 volt current,
and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.

200GB standard 1.8" models in 6Gb operation
(Models ST200FM0023, ST200FM0043, ST200FM0063, ST200FM0083)
Typical power dissipation under idle conditions in 6Gb operation is 2.78 watts (9.49 BTUs per hour).
To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 7). Locate the
typical I/O rate for a drive in the system on the horizontal axis and read the corresponding +3.3 volt current, +5 volt current,
and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.
