200GB standard 2.5” models in 6Gb operation
(Models ST200FM0013, ST200FM0033, ST200FM0053, ST200FM0073)
Typical power dissipation under idle conditions in 6Gb operation is 2.89 watts (9.86 BTUs
per hour).
To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 8). Locate the
typical I/O rate for a drive in the 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.

400GB high endurance 2.5” models in 6Gb operation
(Models ST400FM0093, ST400FM0103, ST400FM0113, ST400FM0123)
Typical power dissipation under idle conditions in 6Gb operation is 3.30 watts (11.26 BTUs per hour).
To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 9). Locate the
typical I/O rate for a drive in the 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.
