If you don't care about warranty, 8 and 12TB drives routinely go for $15/TB on sale inside WD Elements.
I picked up 32TB for just under $500 with discount over the holiday that way.

The theory is that this is a form of market segmentation, where enthusiasts/companies are willing to pay more for a bare drive regular consumers.
For instance, I got all white label WD80EMAZs (256MB cache, non-SMR, same firmware as the Reds) in this batch, so I had to insulate the 3.3V pins.
There are also true Reds, 128MB and 512MB cache drives, helium filleds, 7.2K HGSTs slowed to 5.4K, and other variants.
