The Canon EOS R100 is a 24.1 MP APS-C mirrorless camera that features a single memory card slot and is compatible with UHS-I SD/SDHC/SDXC memory cards.
UHS-II cards will work but you won't be able to take advantage of their faster speeds in-camera, only when copying images over to your computer with a compatible reader.
SD cards support capacities of between 1-2GB, SDHC cards support 4-32GB and SDXC cards support 64GB-2TB.

FAQs
How many images can be stored on a 64GB card?
The number of images that can be stored on a 64GB memory card in the R5100 varies based on the image type that you are recording in. The following values are approximate because file size varies with the scene being shot:
- JPEG L: 7200
- RAW: 2240
- CRAW: 3860
Are CFexpress Type B cards supported?
No. The Canon R100 only supports SD/SDHC/SDXC UHS-I memory cards. CFexpress Type B cards will not physically fit the camera.
What is the difference between UHS-I and UHS-II memory cards?
UHS-II offers much faster speeds (up to 312 MB/s) compared to UHS-I (up to 104 MB/s). This is possible via a second row of pins and two data lanes for simultaneous upstream and downstream data transfer. The extra row of pins are visible on the back of UHS-II cards. Both card types are backward compatible, but a UHS-II card will only operate at UHS-I speeds in a camera that only supports UHS-I cards.
What is the difference between SDHC and SDXC memory cards?
SDHC cards are formatted using the FAT32 file system which is limited to a maximum file size of 4GB. So when recording video clips, the clip will be split every 4 GB but playback with the camera will be seamless. SDXC cards use the exFAT file system which supports a maximum file size of 16 exabytes (EB), so video clips will not be split. SDHC cards support capacities of between 4-32GB and SDXC cards support 64GB-2TB.
