Are there any errors to be found in SMART information, dmesg or syslog? You never can be 100% sure, but I don't see any errors in dmesg/syslog and smartctl shows no errors too: === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health Information (NVMe Log 0x02) Critical Warning: 0x00 Temperature: 49 Celsius Available Spare: 100% Available Spare Threshold: 10% Percentage Used: 0% Data Units Read: 162,228 [83.0 GB] Data Units Written: 135,786 [69.5 GB] Host Read Commands: 430,232 Host Write Commands: 282,975 Controller Busy Time: 2 Power Cycles: 23 Power On Hours: 530 Unsafe Shutdowns: 14 Media and Data Integrity Errors: 0 Error Information Log Entries: 0 Warning Comp.

It is PCIe 4.0 device in PCIe 3.0 slot (as MoBo supports only PCIe 3.0). -- // Lev Serebryakov
