Ive had good luck with used enterprise hdds. They are loud but have always worked fine. I like buying them all at once from the same seller, but I’ve mixed and matched as well.

I personally don’t think smart errors are the end of the world either. A few of them on something large like 14tb isn’t the end of the world. I’ve had more issues with brand new seagate 8tb than anything I’ve gotten used.

I suppose I could pull the entire site and delete the fluff afterwards, but that seems like a very long and resource intensive process for such a small grab.
