    The new refreshed iMacs can use the SDXC card, which holds up to 2TB of data.

    Can this card be used as a backup drive for Time Machine or Super Duper? If so, it as fast as Firewire 800?

    I don't know what else to ask, but if it works, it sure seems like a nice way to go: no external hard drives, no power supply, no desktop clutter, etc.

    Time Machine requires an external HD and 2 TB of data is nothing so even if you could use a card it would be totally impractical. External hd's are very inexpensive these days, just about any would work but IMHO the best out there are:

    OWC's MercuryPro line

    Lacie Quadra D2 line

    G-Tech G series line

    The spec has a 2TB limit. You can't buy cards greater than 64GB currently. 32 and 64GB cards are very expensive. You are better off buying a cheap 1TB USB drive. Get a portable drive and you don't need an external PSU.

    Class 10 cards top out at 80mbps whereas USB can sustain 3 times as much.

    That's the theoretical maximum. Right now SDXC cards max out around 64 GB.

    By the time they reach 2 TB capacity they'll be useless for backup.

    I use the LaCie d2 Quadra - it does a fine job but it's a tad pricey compared to other 1 GB drives. It's fanless and includes all of the interface cables: USB 2.0, FW 400, FW 800, eSATA.

    You could use a 64GB to backup some files... But its too overpriced IMO. You could buy an SSD and house it in an external enclosure eater than doing that.

    Thanks all,

    I did not realize they were so expensive and not even available in bigger sizes yet.
