The Nikon Z 30 is a 20.9 megapixel APS-C mirrorless camera that features a single memory card slot. The single memory card slot supports SD/SDHC/SDXC (UHS-I) memory cards.
The faster UHS-II cards are not supported but are backwards compatible, so they default to the slower UHS-I speeds in camera. You will still benefit from up to 3x faster transfer speeds when copying files to your computer providing you use a UHS-II card reader.

If you want to record 3840 x 2160 (4K UHD): 30p (144 Mbps) video then you will require a memory card that supports a minimum sustained write speed of 18 MB/s. A V30 rated card is the slowest you would need, V60 and V90 rated cards would be fine too.
The Fastest UHS-I SD Cards
If you shoot a lot of continuous bursts and action shots with the Z30 then we would recommend going with one of the faster UHS-I SD cards.
For recording video, as well as using a V30 or higher rated card, we also recommend using 64GB or larger (SDXC) cards, as these avoid video files being split into 4GB chunks.
