Ctrl+Shift+Click or Ctrl+Shift+Enter will launch most things as elevated. Works in Start, taskbar, run dialog, explorer, etc.

I have a Synology NAS and it makes it all pretty easy. To replace/upgrade a drive you basically just take one out and put a new one in. Then just wait for it to finish and then move on to the next drive. Last time I upgraded my 4 drives took a couple days but was painless. Raid is great.
