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?
The last sata controller (onboard or otherwise) that I had with known data corruption and connection issues is old enough to drive now
There are nvme to sata adaptors. It’s a little janky with these as you’ll need to leave a cover off to have access to the ports.
Would you not simply buy a regular NAS?
Why buy a tiny, m.2 only mini-NAS if your need is better met by a vanilla 2-bay NAS?
I have been running usb hdds 24/7 connected to raspberry pi as a nas for 10 years without problems
I've never heard of these disconnects. The OWC ThunderBay works well.
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.
