> The reported SSD lifetime is reported to be around 94%, with over 170+ TB of data written

Glad for the guy, but here are a bit different view on the same QVO series:

    Device Model:     Samsung SSD 870 QVO 1TB
    User Capacity:    1,000,204,886,016 bytes [1.00 TB]

NB you need to look at the first decimal number in 177 Wear_Leveling_Count to get the 'remaining endurance percent' value, ie 59 and 60 here

While overall it's not that bad, losing only 40% after 4.5 years - it means what in another 3-4 years it would be down to 20% if the usage pattern wouldn't change and the system wouldn't hit the write amplification. Sure, someone had that "brilliant" idea ~5 years ago to use a desktop grade QLC flash as a ZFS storage for PVE...
