The Sony A6400 is a 24.2 megapixel APS-C mirrorless camera that features a single memory card slot that supports SD/SDHC/SDXC (UHS-I) memory cards. UHS-II cards can be used but there is no in-camera benefit.
For photographers a V10 or V30 rated UHS-I card is all you really need. Go with a faster V30 rated card if you shoot a lot of continuous bursts, faster cards help the buffer to clear faster and allow faster transfer to your computer.
For videographers a V30 rated UHS-I SDHC/SDXC card will allow you to shoot 4K 100 Mbps. If you only want to record HD 60Mbps then a SDHC/SDXC V10 is all you really need.

FAQs
How many images can be stored on a 64GB card?
A 64GB card will allow you to shoot approximately 2400 Compressed RAW images or 3250 Extra Fine JPEG images with the A6400.
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 2-32GB and SDXC cards support 64GB-2TB.
