Uncompressed 4k stream @ 30fps and 24bpp would be 5.7 GB/s. The top regular SD card speed, UHS-III, maxes at 0.6 GB/s. SD Express, where a PCIe lane is added, goes to 3.9 GB/s.

So, yeah, going to need at least some compression. Good news is that just a little compression can go a long way.

Even full 4K HDR Blu-ray rips come in at about 30GB an hour.

That's 500MB per minute which just about fits in the 10MB/s of UHS Class 1.

I would consider those fairly standard these days. You'd have to have picked an extra shitty AliExpress special to not have your card meet that.
