I’m planning on getting a NAS but only plan on getting the hotswappable 3+ bay drive. In that case a hard drive going down won’t lose my data as the redundancy is 3X or more. As new bigger drives get cheaper you can just swap them out on the fly without affecting the data. The only thing that would get me would be a hardware failure on the machine itself. I have to look into that but another standalone or add-on to this system is a Blu-ray writer. Storage on those will get up to 200gb soon so it’d be only 5 disks yearly or semi-annually to be really well protected.
