Card reader question
Oct 16, 2013

I'm upgrading to a new camera body, and the new camera will use SD cards.  My old body uses CF cards.

I have a multi-format external card reader (USB 2.0) for my 2011 iMac that I bought at the same time as my iMac to dump the CF cards.  The card reader also has an SD card slot.  I know my iMac has an SD card slot built in that I've never used.  Should I expect better performance from the SD slot in the reader or from the iMac built-in reader?

(Note - I understand that different cards will give different performance in the same reader; I'm looking for an answer assuming the same card in both readers).

Part of my concern is the transition from a mix of older 2GB & 4Gb CF cards to modern 32Gb SD cards.  My new camera's sensor is quite a bit larger, so there's going to be a lot more data per image being pushed through whatever reader I use.
