The ioDrive power consumption varies by device capacity as well as external temperature:

	80GB/160GB ioDrive	320GB/640GB ioDrive	320GB ioDrive Duo	640GB/1.2TB ioDrive Duo
Idle	4 watts	4 watts	12 watts	12 watts
100% Read	9 watts	8 watts	22 watts	20 watts
100% Write	12 watts	15 watts	25 watts [1]	25 watts [1]

[1] The ioDrive Duo is fully compliant with the PCIE 2.0 bus specification of 25 watts and does not require external power. If external power is made available to the ioDrive duo, the maximum write throughput may increase. Any external power source attached to an ioDrive Duo by the external power connector must provide at least 35 Watts per device

Note: This reflects typical power draw at 25° C ambient temperature. Add 3 watts draw when running at the ioDrive's maximum temperature of 50° C ambient temperature. Future product power needs may vary.
