If you’re willing to go that route, check out Zabbix and Icinga2 as well. They’re compatible with Nagios checks but the user interface is better.

‘dd’ works, but I prefer ‘shred’. It does a DoD multi-pass shred by default, so I usually use ‘shred -vn1z /dev/(drive)’. That gives output, does a one-pass random write followed by one-pass zero of the disk. More than that just wastes time, and this kinda thing takes hours on large spinners. I also use ‘smartmontools’ to run SMART tests against my drives regularly to check their health.

A named volume for the config directory for one.

Take it off the charger and see if you get the claimed battery life. Maybe you will, or maybe your 3+ hours of battery time runs out in less than one.

Only if you’ve got it cranking all day. I’ve got a couple of Tiny (they’re Micro, which is the same thing) systems that are silent when idle and nearly silent when running less than a load avg of 5. It’s only if I try to spin up a heavy, CPU-bound process that their singular fan spins fast enough to be noticable.

So don’t use one as a Mining rig, but if you want something that runs x64 workloads at 9-20 watts continuously, they’re pretty good.

If your requirement is a 3.5" drive bay, then maybe check out some of the SFF form factors, like an HP Elitedesk SFF 800 (not the mini/micro). It has the same hardware as the mini, takes the same amount of power, but has a space for a 3.5" disk and a slimline optical disc. It’s bigger than a NUC, but smaller than a tower.

It probably didn’t. What’s probably happening is that when Debian starts, it loads power management, while being in the BIOS/UEFI still has everything at max.
