PSA to always run a full length SMART check for any drives you buy, even from OEM. The short test and log are not enough, I have bought faulty drives that someone had reset the logs and power on hours.

All passed short SMART test, but failed long SMART test after only a few minutes. Found just one drive that the skrub forgot to wipe and the log showed 6 continuous years of power on usage.

Even from OEM, you will at least know if the hardware is DOA which you can then RMA.

I don’t know if mac has something similar, but you can run a command on linux to list all the CPU vuln mitigations applied, and its hilarious to see on something old like a skylake or haswell with the amount of patches that have dropped since release.
