well…its a hit or miss, i recently just got lucky with 2 16tb drives i got for 400, it probably came from a chinese chia server or some shit idk, but i did basic checks like SMART and they seem fine. I had my rx580 years ago also probably from a mining data center.

My logic and xp with these used “enterprise” stuff is that they are definitely used but not as abused like being OCed, etc. because they are optimized to run for a long time unless they are being decomissioned.
