networking - Recommended RAID Mode for Small NAS Array

I am interested in purchasing a NAS array as a home server, and I am looking at currently 4x2TB drives in a 4-bay Netgear ReadyNAS array.


I understand that RAID is not a backup and am will be backing up to other locations, however the current NAS that I have contains only one internal hard drive and I was looking to get one with more capacity and redundancy (so in case one of the drives fails I don't have to restore everything from backups and it is more reliable than just having 1 drive, etc).


Is there a recommended RAID mode for a small 4-bay NAS? I was looking into RAID 5 because I wanted to have more storage for a cheaper price than using RAID 1 and having to purchase double the capacity. Is this an okay solution? Or is there another mode for this scenario considered better?
