Although some new formats like XQD and CFexpress have come along, the SD memory card format is the most commonly used in cameras. It’s also compatible with the memory card readers that are sometimes built into laptops and computers.
SDXC cards can be made in capacities from 32GB to 2TB. So while Kingston makes a 32GB Canvas React Plus SD card, it’s an SDHC card rather than an SDXC card.
As a UHS-II card, the Canvas React Plus has two rows of contacts visible on its back to enable fast data transfer rates. It’s rated as a V90 U3 card and has read speeds of up to 300MB/s and writes speeds of up to 260MB/s. As such, it’s capable of being used to store 4K and 8K video.
Kingston supplies the Canvas React Plus card with MobileLite Plus SD Reader. This has a USB-A type connector that is USB 3.2 Gen 1 compliant and therefore has transfer speeds of up to 5Gps or 625MB/s.
