Running Incus on a headless Debian 13 host using a Ryzen 2700 CPU with an uptime of at least 200 days, no issues. Really like the ability to seamlessly pass through a GPU on any container running the same kernel. Used to run ESXi, never looking back.

I’ve had good experiences with both WD and Seagate. According to industry, most HDDs will last at least 3-5 years if they are used regularly, but you can also monitor their health via a number of tools for better lifespan estimation, e.g. smartctl and smartd on Linux. Risk management and a good hardware failure mitigation strategy will ultimately help protect your data for the long run though.
