I wouldn't rely on SMART. I have a broken drive, which has lots of badblocks - but SMART happily claims it's fine (short/long tests are completed without errors).
If you haven't seen Google's hard drive study yet, you should take a look. It's at http://labs.google.com/papers/disk_failures.pdf The conclusion says that "some of the SMART parameters are well-correlated with higher failure probabilities," but also that "a large fraction of [google's] failed drives have shown no SMART error signals whatsoever."
