    As we all know, Apple is sometimes behind the technology curve compared to the PC world, and I wonder how things are with card readers. For example:

    Lexar launches 500MB/s USB 3.0 CF/SD card reader

    Now, I understand there is no support for USB 3.0 in OS X. However, I'm asking about the card formats. I know OS X supports SDXC, but how about UHS-I? I have a new camera that uses UHS-I and I know Apple can be lame about supporting new formats, getting them late if at all. So how is UHS-I support in OS X? If there is none, then it doesn't make sense for me to get this reader :(

    I haven't yet found a card reader that wouldn't work with my Macs.

    It's not OSX to support SDXC, it's the built-in readers. They have to work with SDXC on controller level. An USB card reader will present the OS with whatever card has been put into the reader, since they are all seen by OS X as a volume, the reader itself does the processing (using its own controller).
