On the card itself, it says SDXC. In addition, ifWiki
does not lie, then SDHC cards can not be more than 32GB. And any 64GB card is SDXC.
I was interested in the SanDisk support team about the differences between the two cards. Here's what they answered:
"The codes that you provided carry only production information. As a buyer, you will not find any difference between them."
The codes in question are card markings; SDSDQY-064G-U46A and SDSDQUA-064G-U46APost has been editedoldos - 09.05.12, 01:24
