salut ! it works tiptop for me with the ps4 pro (small side note: by the way, i had first tried to save the game saves on an external hard drive, which didn't work. there was nothing to read anywhere about this fact, that it has to be a stick, neither in general on the net nor on the sony-ps4-homepage. it was a little nerve-racking odysee to find this out). and the sandisk 1 gb has worked perfectly so far (in use for a few months) and is first-class and robust. however, the data volume of the game files is smaller than i expected (as a gamer, i'm a beginner). so a 128 gb stick would have been sufficient. unfortunately, i can't say anything about the ps5 due to the delivery bottleneck, but it will probably be identical. best regards and good luck !
