San Disk 64gig is as big as I've found and RT will support it with no problems. I've heard sdxc is capable of 128gig and there are some out there, but I haven't found them in the micro size. Technically sdhc is up to 32gig, but I've heard about a few people using 64gig cards if it is formatted right. Don't hold me to that. Search forums for more info.
