(all kinds of options there, freenas is awesome too) With unraid if you have a 4 drive array one of which is parity, and want to expand, either a) replace a smaller drive with a larger, or b) add a drive to the array. ![]() Expanding the array later then either requires increasing the size of all drives, or setting up another array. There is a cost of entry (gotta purchase a license) but it doesn't take as much pre-planning and initial outlay as something like freenas where you have to have matching drive sizes for the array you want to set up.

They take what they take,) you can use a mix of drives, support for up to 2 parity disks allowing for the loss of 2 drives without data loss. Pros: Easy setup, low resource usage (unless you want to run a bunch of vms/dockers etc. Got the cabling fixed, let it rebuild and voila', no issues, no lost data. As for recovery, I did have a cable go bad. ![]() To reconstruct write, the writes are MUCH faster even without cache, so I'll probably end up just using the cache drive for my vms. I have a 500G ssd in there as a cache drive, but after going in to disk settings and changing the Its now up to about 10T usable space with a 4T parity drive. ![]() Currently I'm running plex media server, sabnzbd with vpn, sonarr, and couchpotato as dockers, and have an ubuntu vm running. I've since updated to an old dual cpu xeon with 24 threads and 24G memory and it runs really nice. Started with a very cheap commodity server and stuffed all the old drives I had laying around in it.
