I just checked using $ sudo smartctl -a /dev/nvme0n1

That's after about 2 years of use. I think SSDs can take quite the beating nowadays.

View on HN

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):

    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).

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.

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.

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