WD Red Plus
8 TB, 3.5"
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. (https://www.digitec.ch/de/s1/product/wd-red-plus-8-tb-35-cmr-festplatte-40076322) WD Red Plus 8 TB, 3.5", CMR with 128 MB cache costs 292.88 today --> + 56.6% !!! (https://www.digitec.ch/de/s1/product/wd-red-plus-8-tb-35-cmr-festplatte-18807934) 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?
