Dunno, if shucking is an option, external consumer WD drives are regularily available under EUR 200 for 10 TB, while bulk drives of same capacity or higher for dedicated storage use are at least 50% more expensive. In my experience this is a releatively new development, that those two markets diverged that much. 2015 and before bulk HDD where usually cheaper than external ones. If you do care about warranty you can just keep them in the external usb casing and enjoy having an abundance of power supplies and USB 3 cables. If it's 24/7 hot storage it also uses 50kWH per Year at 6W. That's also about 15EUR/Year minimum energy costs per drive. Me feeling is, that all HDD manufacterers are extracting as as much value from the market as they get away with (meaning having more of a smell of informal price fixing, then of free market) while they still can, before they will be made osolete to solid state storage in 5 years latest.
