I would like to buy WD Red 8 TB for my NAS. Now the question is whether 128MB or 256MB cache.
Actually, I think that more cache is better.
But why are the HDs with more cache so much cheaper (over 50%) ??? Doesn't that make sense?
Two examples (as of 10/11/2024):
WD Red Plus 8 TB, 3.5", CMR with 256 MB cache costs 187.- today.

WD Red Plus 8 TB, 3.5", CMR with 128 MB cache costs 292.88 today --> + 56.6% !!!

or for the Pro series:
WD Red Pro 8 TB, 3.5", CMR with 512 MB cache costs today 213.-
(https://www.digitec.ch/de/s1/product/wd-red-pro-8-tb-35-cmr-festplatte-43883142?tagIds=76-535)
WD Red Pro 8 TB, 3.5", CMR with 256 MB cache costs 259.- today --> +21.6%!
(https://www.digitec.ch/de/s1/product/wd-red-pro-8-tb-35-cmr-festplatte-8766620?tagIds=76-535)
Why is that? Am I missing something? Who buys the version with less cache?
