Question regarding these mini pcs: how do you connect them to plain old hard drives ? Is thunderbolt / usb these days reliable enough to run 24/7 without disconnects like an onboard sata?
I've run a massive farm (2 petabytes) of ZFS on FreeBSD servers with Zraid over consumer USB for about fifteen years and haven't had a problem: directly attaching to the motherboard USB ports and using good but boring controllers on the drives like the WD Elements series.
Good question. I imagine for the silence and low power usage without needing huge amounts of storage. That said, I own an n100 dual 3.5 bay + m.2 mini PC that can function as a NAS or as anything and I think it's pretty neat for the price.
I have experienced them - I have a B650 AM5 motherboard and if I connect a Orico USB HDD enclosure to the fastest USB ports, the ones comming directly from the AMD CPU (yes, it's a thing now), after 5-10 min the HDD just disappears from the system. Doesn't happen on the other USB ports.
Well, AMD makes a good core but there are reasons that Intel is preferred by some users in some applications, and one of those reasons is that the peripheral devices on Intel platforms tend to work.
