WD has some direct for £80 but they are Shingled drives which are prone to slow downs. Will have to investigate the Ironwolfs.
If you are using them for back up, then SMR will not make any difference, not so great in a raid system as it may slow things down, but for normal use you are not going to notice much difference I doubt.
The Toshibas I have in my NAS are CMR, Cost me £300 for two 8TB n300 drives. £191 each now for the 8TB ones.
I only went for the CMR because i have them in a raid system in my NAS, otherwise I would have gone for SMR
