Don't go single bay. Go 4 bay and set up RAID-6. This way, any two drives can fail at once and you won't lose data. This actually happened to me once. One drive went bad and the second drive went bad while I was waiting for the first replacement to re-sync.
It gives you extra protection from data loss when a drive inevitably fails. Keep a new replacement drive for when one fails.
Schedule an integrity check once a quarter, and you are protected from bit-rot.
Do regular backups to an external drive for the important stuff. Remember, this is where you're keeping your family photographs and your important financial and legal documents.
If you are really serious about covering yourself, keep your backups off-site, so you're covered in case of fire, flood, or military shelling.
