Should work, according to my understanding.
I currently use the following as storage for photos without any problems
the ultra-fast EVO Plus microSD card (with SD adapter, from Samsung) with UHS-I speed class 3 (U3) with a write speed of 90 MB/s (like a V90 memory card)
gives only a minimal delay when transferring data; should also work well for 4K UHD (no own experience in this regard yet).
m.f.G.
