FYI you probably shouldn’t be saying you feel really comfortable with your data safety while suggesting unraid. The way unraid handles it’s storage will lead to data loss at some point. Unraid only locks down an array and protects it when smart starts issuing warnings that a drive has failed. Smart isn’t magic though and when a drive starts to die it might start writing garbage data for days if not weeks before smart catches on. If a drive writes garbage for long enough there’s nothing you can do to fix it due to that way unraid handles arrays. This is why ZFS is such a popular option as it treats hard drive with a level of skepticism and verifies the data was actually written correctly along with verifying the data from time to time.
That’s not even mentioning unraid is charging for what other software does for free.
