Don't have any questions. Just wanted to say that Acer Nitro 5 is compatible with NVMe M.2 SSD
And if you have some issues with it after installing (computer don't see the SSD), do next:
1. Open "Disk Management"
2. Check if your disk offline or not there
3. Click with the right mouse key on it and make it "Online" - then you will be available to transfer data from disk C there (I used Samsung Data Migration for that)
The last two pics - proofs that Samsung 970 EVO Plus in installed (don't want turn off the computer, to show that I have Acer Nitro 5, that's why I show my characteristics from NVIDIA GeForce Experience)
P.S. Picture with the "Disk Manager" screenshot was taken from the web, because I use all disks and don't have options to make it "Offline" and "Online" back for this manual.
Thanks for the attention!
