I was a bit off, they were 15% cheaper than the Ironwolf on the same website/from same seller (156, not USD, vs 179, not USD).
For a better comparison, I went to WD’s official store and for what I spent on these two 8TB Exos (312, not USD) I can get two 4TB Red Plus (310, not USD). Can’t make a direct comparison with other Seagates because their “buy now” section redirects me to Amazon, which, as you said, is not the best since they allowed third party sellers, but on there the 8TB Ironwolf is 250 (!!).
As you already know, I’m not in the US so I can’t buy from there. Unfortunately, Seagate’s “buy now” section (which should be official retailers) brings me to either Amazon or other chains that don’t have much else besides portable drives.
At this point I have two options, really: try again the same online store (which is kinda like Amazon, many third party sellers), but getting Ironwolf, which should be more likely to be “legit”, and of course check them as well when they arrive, or settle for two 4TB WD Red Plus (which isn’t ideal as I’m already nearing 2.5TB total, but should allow me to get by a while longer) bought directly from WD.
edit: looking at the link you provided, I paid 30% less for my Exos. Would that sway you towards keeping it without warranty (apart from the seller’s, which is one year I think)? Mind that I don’t need enterprise-grade drives, and I think even NAS drives are overkill for my needs. For example a WD Blue with its 55TBW per year might be enough for me (that’s 150GB a day everyday for a year, which is above my average writes), but those don’t come big enough (I need 6TB min to be comfortable) nevermind, they do come in 8TB size, just at a lower spinning speed (5640rpm), but they cost more (267) than the Ironwolf, and are SMR and have 128MB cache. Sounds like a bad deal!
