So i need to pick up some new hard drives, and are the server grade drives worth the extra money? Newegg has the WD 500GB drive for $104, and i already have one of these and love it. The drive is quiet, runs cool, and has fast speeds. Then there is the RE2 drive, their enterprise grade, for $129. I leave my PC on 24/7, so would i be safer with these drives, or is it just not worth it for a standard PC. I do transfer large video files between drives fairly often, so i'm looking at ware and tare.
