    "Great basic home NAS with RAID. Easy setup and operation....RAID is the way to go...I bought this to replace my original that is no longer secure. I like the RAID option as my items are backed up twice. I have this in my fireproof safe with family photos, good alternative to paying for a cloud subscription."
