I just got a Crucial T700 last month which is a PCIE Gen5 x4 NVMe M.2 drive. I put it in an ASUS PRIME Z890M-PLUS motherboard with an Intel Core Ultra 7 265K Started to install Fedora Linux version 41. The drive would just completely disappear from the OS and the kernel would report I/O errors on a missing device. Sometimes this happened during the initial install. Sometimes 5 minutes after the install when starting a terminal. I couldn't even type "ls" because the "ls" command is on the drive that went away. Saw reports of PCIE Gen5 incompatibilities so I moved it to a Gen4 slot and then it worked. But the machine had so many other random crashes and errors reported in system logs saying "This is a hardware error not software" and stuff like that. Returned it all. Just got an AMD Ryzen 9 9950X and Gigabyte X870E AORUS PRO The Gen5 drive seems to be working at Gen5 speeds. lspci -vv shows 02:00.0 Non-Volatile memory controller: Micron/Crucial Technology T700 NVMe PCIe SSD (prog-if 02 [NVM Express]) LnkSta: Speed 32GT/s, Width x4
