    OK, the first SDXC products have been shown at CES.

    Now we need exFAT support in Mac OS X.

    Why?

    What are SDXC products and why does it mean OSX has to adopt exFAT?

    SDXC is the latest in the line of specifications for SD flash memory cards. First there was SD, then SDHC not SDXC. Basically it allows for higher capacity and faster SD cards. That said whilst there were a few cards shown at CES there were not many devices to actually use them in. There is probably at least a year before this becomes an issue. Possibly more: if you buy a digital camera that uses SDXC and connect it via USB to your Mac then it won't matter if the Mac understands SDXC or not: it talks to the camera via one of two protocols and the format of the underlying storage is handled by the camera.

    Ok thanks.

    Looks like we'll see a usb3 port before sdxc support if any.

    I suppose until it (if) becomes mainstream apple isn't going to move on this.

    That some cameras allow you to access the contents of the card via a protocol is no excuse.

    The Mac should support exFAT to allow the use of card readers and cameras which present themselves as a USB mass storage device.

    There were several cameras shown with this technology.

    The MSRP of the cards starts at $400. :eek:

    Microsoft has not published the exFAT specification, has a patent pending, and has established a commercial licensing scheme.

    I think that OSX should support it when you can actually buy the product. I imagine that if it gets popular (this is really not guaranteed yet) Apple will add support via a 10.6.x update.

    If Apple choose not to or take too long support can certainly be added by third parties, most likely via MacFuse.

    The cards will ship in February. I don't know about the cameras.

    I still haven't seen an SDXC reader.

    The SDHC specification stops at 32GB. There are already 32GB cards.

    The Compact Flash specification stops at 128GiB, and there are already 64GB cards.

    SDXC will succeed just because it shares the same physical form factor as SD, like SDHC (which required the change from FAT16 to FAT32).

    Unfortunately I was not able to connect a Panasonic HDC-TM707 with a 64GB Panasonic SDXC card to a new MacBook i5. The MacBook is not able to detect the card - neither in the camcorder and also not in the SD card slot of the Macbook 8-(( There is no way to work with these SDXC cards. A 32GB SDHC works well.

    So the camera doesn't show up in Image Capture? I'd not expect it to show in the Finder...

    Exactly. Kind of "The data medium is not readable. Do you want to format OR ignore?" message pops up. In case that I format the medium (i.e. the SDXC card in the camcorder that is connected to the MBP via USB), I receive afterwards an error message from the camcorder (asking me whether he should format the card). For the moment it seems that there is No Mac support for the new SDXC cards; the SDHC cards (up to 32GB) on the other hand work well.
