Power Consumption of Micro Sd Cards and effect on battery life

I was wondering if anyone has any information regarding the typical power consumption of the Various MicroSd Cards on the market and the effect of battery drain on the Kobo devices. I googled and found this on Wikipedia but as to the reliability of the information I do not know.

Power consumption

The power consumption of microSD cards varies by manufacturer and model. During transfer it may be in the range of 66–330 mW (20–100 mA at a supply voltage of 3.3 V). Specifications from TwinMos technologies list a maximum of 149 mW (45 mA) during transfer. Toshiba lists 264–330 mW (80–100 mA).[65] Standby current is much lower, less than 0.2mA for one 2006 Micro SD card.[66] If there is data transfer for significant periods, battery life may be reduced noticeably (smartphones typically have batteries of capacity from 1000mAh to 2000mAh).

What I was wondering if anyone might be able to provide a deeper insight to this particular question? Any and all comments are welcome.

Regards
