I have an asus x570 pro with an inland premium m.2 1tb for boot and some storage. I was just using for sim racing, but hurt foot and now into gaming and drive is full. This board has a 2nd m.2 but that goes to the chipset. Wanted to take advantage of pcie gen4 so was looking and got an amazing deal on 2TB wd sn850 with heatsink. Looked on web and seen nothing but huge issues getting this to work on 570mb. slow speed, not recognized on cold boot. everything horrible stories. I've pretty much figured that the 2nd chipset slot won't give me advantage of 4.0 anyway so probably pick up 970 evo or something. Anyway, I was able to cancel the sn850 order, but I now learning that WD came out with an update that fixed these issues in July. Wondering if anyone who had issues with sn850 tried update and it works now. Probably still could get deal on 850 and use as pcu slot if needed. So has anyone tried this update with an x570 MOBO?
