Doesn't even need a sled…. That’s great if your volume fits onto a single hard disk. I use 4-5 bay NASes because I have more than 8 TiB under management, and want volume level redundancy on top of that. That means 4+ 4 TiB disks, at minimum, which means I need another like-kind NAS to backstop the first.
