a dedicated RAID controller with battery is by far the best option to go with.
the battery is there just in case of power loss so that it can hold the data in memory and commit the data once power has been restored. Just make sure that the RAID controller has sufficient RAM (512MB or 1GB is recommended)
This is how i build servers at work.
unRAID is good i personally use FreeNAS, even in my vmware LAB at work.
You can use it to do backups and run VM's or vmware with iSCSI. the documentation is excellent and the application is feature rich.
You can start on it with the bare minimum of services and build it to be an enterprise solution.
I'm confused by your post. You say to stay away from ZFS in the first sentence and then go onto recommend FreeNAS which is exactly that. You then go on to say a dedicated hardware RAID controller is the best option, but in recommending UnRAID and FreeNAS (both of which require disk pass through aka IT mode) you are recommending against that notion.
As to your statement about being stuck with the size of the volume you originally setup, that is only partially correct. Yes, that particular vdev can not increase in disk size (though the size of the disks can all be upgraded at once), you can create additional vdevs to the same zfs pool to increase the overall storage capacity.
Your post is kind of all of the place and full of contradictions. Not trying to call you out but it's definitely going to be confusing to others.Edited by PuffinMyLye - 4/26/17 at 9:22am
