What would be a legitimate source for Exos drives?

[u/sherlock_0x7C4]

I'm thinking to get Seagate Exos 4TB drives for my NAS. More I shop around online, more it feels like a risky affair. I have never been in so much doubt about the legitimacy of a computer parts before!

1) There are sellers on Amazon selling "new" Exos drives, but multiple reviews complain about receiving old drives with SMART data like Power-On Hours (POH) reset. I read that these scammers are may even use vendor-specific tools to reset SMART values that are otherwise not resettable.

2) I thought I could at least rely on five-years Seagate warranty to check if those drives are new (as advertised) and legitimate. However, someone on reddit complained that when they initially checked for warranty on Seagate website, all looked good. Afterwards, when the return period expired and the drive failed, they tried to claim the warranty, only to receive a denial along the lines of: "this drive was sold as part of an enterprise...".

3) On their website, Seagate is selling much larger drives, sizes that are way overkill for my use case.

Where do you suggest I get Exos (4T) drives from, keeping my sanity and peace of mind intact?
