It certainly could. That's the gamble you're taking.

I usually replace drives after 5 years if they are doing anything I consider important. So those drives to me would have 1-2 years left in them. Of course, I have seen a good number of drives I have repurposed to things less important still manage to rack up impressive numbers of hours.

Depends on the usage. That's the gamble you take. I would maybe buy three and put two in a mirror and keep the third one as a replacement?

That's 240$ for three drives without warranty though... Nevermind I'd prefer to buy two new Toshiba X300 new for 210$ a piece and forget the headache and get the warranty.

Sometimes you get what you pay for ... Sometimes

It could. I'm not trusting it with anything important though.
