that's why you should use raid6 (allowing for dual failures)

And, if possible, try to use drives from a couple of different batches. I wouldn't go crazy trying to do this, but sometimes a combination of drives from two or three batches can make a difference (though not always).

Also, a very informative read: http://research.google.com/archive/disk_failures.pdf
In short, best thing to do is watch SMART and be prepared to try and swap a drive out before it fails completely. :)
