So, I have an old 3rd or 4th gen Intel NUC that’s I used to use to run Kodibuntu back in the day. I’m thinking of repurposing it into a low power home server to run the *arr suite, Jellyfin and nextcloud plus maybe some other bits. Nothing too taxing that I can see.
Obviously I need hard drive space to go with this. Is a USB enclosure, directly attached, going to be fast enough? Or do I need to go to a NAS of some kind? Alternatively, my router has a USB connection for a HDD - would that be better?
USB is fine, but remember that if the plug comes out, you can get corrupt data. Make sure you use a really good journaled file system. No FAT partitions.
USB 2.0 maxes out at 480Mbps, so won’t even saturate a gigabit network connection. And you won’t even reach that for a USB Mass Storage device. So, make sure you’re using USB 3.
