Dilemma here: I had a drive go funny in my RAID; I don't know what happened, but it turned itself off and spun back up. I got a bunch of warnings about a failing drive and then I tested the drive. That was about 4 months ago. It has been running fine ever since until today. Another hiccup you could say. No SMART errors or anything. I don't even see anything in the logs. Problem is I'm worried it will fail without notice than them my RAID will be in reduced mode. The drives I have are a generation old, but they still sell for a lot; so do I get a backup drive just in case? I'm at a dilemma because the drive I would need is still like $190 for 300GB (VelociRaptor)! That's just ridiculous. I will be upgrading to SSDs in the future (when prices come down a bit more), but right now this is workhorse. Thoughts?
