What is the difference in performance between “SanDisk Extreme Pro 64GB SDHC (SDSDXXG-064G-GN4IN)” and “SanDisk Extreme PRO 64GB SDXC (SDSDXPA-064G-X46)”? Their numbers look similar, except the SDHC says V30 on it also.

both the cards you mention are SDXC cards. All cards 64GB and higher are SDXC.

Both cards are the same performance the one with the V30 logo is just a bit newer. V30 is a new logo for SD video performance.

Thanks for the reply. So no difference in those two? Why does the V30 one say SDHC though? Thanks

you would have to provide a link to what you are looking at. if it is 64GB it is SDXC.
