At that point you can still fall back onto swap on NVME.

Doesn’t Apple use pretty damn quick NVME? I wonder how much of a performance drop it actually is. Certainly not as bad as running a swap file on a 5400 rpm HDD…

  • Isn't that NVME also very expensive to replace because it's tied to hardware identifiers? If you keep swapping all the time, surely NVME would be the first part to fail

    • This was heavily debated in the 11.4 timeframe because there was risk that this version of the OS could excessively wear NVME.

      The issue was subsequently resolved but the consensus was with modern wear leveling this isn't so much a thing.

      I have a 2021 MacBook Pro with the original drive. I use it heavily for development practically every day and just dumped the SMART data.

      Model Number: APPLE SSD AP1024R

      SMART overall-health self-assessment test result: PASSED

      Available Spare Threshold: 99%

      As always, YMMV
