I just checked using $ sudo smartctl -a /dev/nvme0n1 Percentage Used: 2% Data Units Read: 7,173,143 [3.67 TB] Data Units Written: 22,666,414 [11.6 TB] That's after about 2 years of use. I think SSDs can take quite the beating nowadays.

You write 3x more than you read? Seems like a strange access pattern. Maybe something is going haywire with logging?

  Could be a log ingestion server or surveillance camera recorder.

The oldest NVMe SSD I have at home is a Samsung 950 Pro (the 256 GB version!) which I bought in late 2015 IIRC (and put on a ASUS Z170-A mobo, that already had a NVMe slot) and which has been in use that whole time (but mostly light desktop use): Percentage Used: 27% Data Units Read: 48,801,760 [24.9 TB] Data Units Written: 84,590,914 [43.3 TB] Power Cycles: 228 <-- only 228 power cycles in 11 years, that's about 17 days uptime every time I think Power On Hours: 37,153 <-- not sure about this one, this comes out at about 9 hours / day of uptime And after 11 years it's still going strong! Now it's not on my main computer anymore: I'm rocking a WD-SN850X (recommended here on HN when it came out) but the old Samsung 950 Pro is on the desktop computer my wife uses daily (and she WFH). > I think SSDs can take quite the beating nowadays For regular use definitely. In my servers I've got ZFS in mirroring though: you never really know when a drive is going to RIP.

They can yes but they do need to be powered at least once a year or they'll lose data too.
