Hi, compared to the AV PRO SE 1785MB/s version, on the z8, will it have the advantage of heating less? Thank you :)
One interesting fact is that the Angelbird CFExpress V4 B Performance Card Reader has a fan in it. Those cards must run pretty hot. The older CFExpress B 2.0 cards must not need a fan, and the reader is much cheaper.
The Angelbird AV Pro SE CFExpress B 2.0 has a power usage of 0.45 W at idle,and 2.40 W Max.
The Angelbird AV Pro SE CFExpress v4 B has a power usage of ~ 800 mW at idle, and up to 3.75 W Max. High power usage means more heat.
