Let's not truncate this sentence to avoid altering its meaning. I certainly don't deny four drives NAS exist but I think dual bays are still a lot more common.
Anecdotally I know a lot of people with one drive NAS (some ISP provide them here), a few people with two drives NAS (including me) and no one with four drives (but I don't know anyone heavily into photography or video which seem to be the main usage).
My point was that you can still address a large segment of the home users market without RAID 5 and RAID 6.
