I have a Gigabyte X570 Aorus Ultra with AMD Ryzen 7 3800X.
To boot WIndows 10, I use a Sata SSD 1TB bootdisk and to store my important data, I use 2x Samsung SSD 980 Pro 2TB, PCIe 4.0 NVMe M.2 in RAID 1 mode (RAIDXpert2).
My RAID 1 data is backupped every night, but the most recent data is always on the RAID 1.
Recently one of the NVMe started to have issues but was still working.
I inserted it into an NVMe to USB C converter on another computer and was unable to read any data of it.
The reason I use RAID 1 is to save guard my data and with Intel RAID I have been able to access one of the disks externally when the computer died.
