Will this card record 4K video?

Yes. Its U3 and V30 ratings meet the sustained write speed most 4K cameras require.

Does it work in a UHS-II card slot?

It fits, but it runs at UHS-I speed. You will not get the extra UHS-II bandwidth.

Is 512GB enough for a long shoot?

For most stills shoots, yes. For 4K video it depends on bitrate, so check your camera's recording time per gigabyte.

Is it good for 8K video?

No. 8K and high-frame-rate pro codecs need faster UHS-II or CFexpress cards.

The card itself. No reader or case is included.

Our take on the Samsung PRO Ultimate MB-SY512SB Flash memory card 512 GB SDXC UHS-I

The Samsung PRO Ultimate is a 512GB SDXC UHS-I card built for cameras that shoot high-bitrate 4K video and long bursts of stills. It is rated U3, V30 and Class 10, so it meets the write-speed floor most 4K camcorders and mirrorless bodies ask for. Against UHS-II cards it gives up peak speed, but it runs cooler and works in the many cameras that only have a UHS-I slot. Owners rate it highly for reliability and sustained writes.
