Hi everyone! I've encountered an interesting issue. My Samsung EVO 128gb microSD ocassionally starts to work at very low speeds (about 21 MB/s) and keep working like that until I format it. I have sd_uhs hack loading at startup. Things I tried: removing battery, different croprec modes, older ML builds, recording RAW video without croprec, loading sd_uhs manually, loading sd_uhs in photo mode and etc.
And the most interesting thing is, after I formated the card on my PC write speeds returned to normal. BUT, after some tests with ML (I tried using silentpic.mo with 4k croprec preset on 1/4000 shutter speed) my camera froze (so I had to remove the battery), and after 3-4 more crashes like that I decided to check if I am still getting nice write speeds. And guess what, my microSD card starts to underperform once again. This time I decided to format it in camera and it helped.
Any thoughts about what exactly casing it? Is there any way I can fix it without formating my card?
And, I would be very grateful if somebody makes a working silentpic.mo as 4fps burst speed is too low for my needs.
