I have been looking at flexraid, and would like to ask a few question from people in the know, I currently have 3 hdd's installed, One with the OS on (WHS2011) and 2 x 1TB drives for storage, I would like the 2 TB drives to show as 1 drive and i believe i can do this with flexraid, The questions i have are..... 1. If i use flexraid will i lose existing data on the drives? 2. Can i add another drive to the pool as and when i buy one? 3. how safe is it?
