It is FAR safer than RAID 5 in my opinion because the data isn't striped in Unraid- you can pull each disk out and access the data on it. With RAID 5 if the array fails (because one more drive fails then the number of parity drives) bye bye all your data.
That reason is part of why I switched from Ubuntu+RAID 5 to Unraid. The other part is that the lack of striping lets disks sleep, which saves power and extends their life.
