For more than 2 years (12/07 - 14/10) three plates converge in a QNAP TS-419P II, however, with less than 2500 hours. I do this NAS to only when necessary. One of the three plates has 2 "Reallocated Sectors". I would have expected that the plate has less error in view of the small hours. I have specially the 4-slot NAS equipped with three plates in order to migrate to online 6TB plates, when the plates start to weaken. Unfortunately, the 6TB plates seem to make more mistakes at the time. Hence my three still have to keep something. let's hope the best...
