Do you have a habit of checking your disk health? I check mine every month to prevent disk corruption and data loss.<p>If you are interested in smartctl, here is a demo: <a href="https://x-cmd.com/1min/smartctl" rel="nofollow">https://x-cmd.com/1min/smartctl</a>
smartctl recently helped me nail down some nasty slowdown issues with Proxmox running on an Intel NUC. the problem turned out to be that the box was running really hot!<p><pre><code> smartctl -A /dev/<device> | grep 'Temperature:'
</code></pre>
i bought a small USB-powered clip-on fan, plugged it into the NUC and instead of ~75C the NUC is now running at ~32C and speed is as-expected.
