I purchased some WD 2TB drives and this http://www.newegg.com/Product/Product.aspx?Item=N82E16817821003&cm_re=hard_drive_dock-_-17-821-003-_-Product dock to run backups using Arcserve. It seems like the dock is failing after about an hour of constant backup (our backups run around 3-5 hours long). I need to find a dock, preferably USB 3 that will be able to take constant writing for long hours. Can anybody help me out?
