ReadyNAS Ultra 4 + slow to resync last HD

Exactly 10 minutes later after my last post (9:51), the Resync Process got from 22.9% to 37.8% and never got behind 105 Mb/sec in terms of speed. Should be finished in 45 minutes. Like I said, I know those are only 500Gb drives, but if we calcultate this based on a 2Tb drive, from the same brand..., it would take 4 hours to resync if we consider that a 500Gb drive takes 1 hour, that's good for me compared to..., sometime more than 300 hours for the Green drives!

I will post a final post on this thread when it finishes, just to let all know what it writes.
