This article may be helpful: Difference between Speed Class, UHS Speed Class, Speed Ratings (performance) and Video Speed Class for SD/SDHC/SDXC cards, also this product has all SanDisk lines to compare: SDXC/ SDHC/ SD support information page

I suggest to get a card with Vx rating, that would guarantee sustained write speed of x, so in case of SanDisk that would be Extreme Plus or Pro with V30 or greater rating for 4k video
