Which one has higher stability. I am planning to replace my two WD raid edition 3s in raid 0. I don't quite like the large amount of vibration from the WD RE3s and im almost out of drive space anyway. I was thinking of dual Samsung EcoGreens since they are ultra quiet and 5400RPM so low vibration too. Then again I want stability, best if I get a enterprise raid level drive. Do 5400RPM green drives have good reliability. I imagine that they are better than 7200RPM drive and since manufacturers don't make raid level drives at 5400RPM. Can someone confirm the stability of green drives.
