Speed is as advertised, cheapest Pcie 5x4 ssd in the market and definitely the best one without a DRam cache. Temperatures are good with the heatsink included in the motherboard.
Got 14k reads like it was promised in a bench test
I found that in the m.2 #1 socket, no go, that was under the video card which is in the second slot from the too big ryzen x399 cooler. So I looked in the manual and went to #2 m.2 socket and my computer detected the 1TB drive. Then it was a matter of unplugging the spinning disk drive and using an old 1909 windows 10-64 downloaded disk from way back and it loaded windows 10. Then installed many old programs I like then to Update and Security to get version 22H2 by download. The drive is now my primary hard drive and this is a first time for me with M.2. I bought this with the heatsink so I don't have to worry about that. Everything works.
