SanDisk 128GB Gameplay microSD Memory Card

I got this SD card so that I could install and run games directly off of it, freeing up space on my hard drive. I paid extra for the higher advertised read/write speeds. Two tests confirmed that the card was getting no where close to advertised speeds. Actual benchmark running Cyberpunk directly off the card were very similar to running the game from my SDD, except that you can see in the pic that the minimum FPS was 3, which means it had some stuttering. Average FPS was close to my computer's benchmark off the hard drive. Looks like I'll be able to use it as intended, but it's disappointing that the read/write speeds I've seen were not at all close to the advertised number.
