Well then very little of what I said actually applies!

Unless you know the hours on a drive, you might get brand new ones, or you might get ones with 50k hours on them. They may also be from the same batch, which isn’t ideal for data durability. If you’re ok with all that, then go for it. I generally don’t buy used drives because I don’t want to take the additional risk.

I’d be surprised if you can’t find a better deal on used spinning rust though… the shipping alone is probably half the value on a good chunk of sales from SmS.
