For home use it's a completely unnecessary layer of complexity that is a pain to recover from. If all you're doing is duplicating data, there are ways to do that that don't require any configuration if your OS dies, or say your motherboard dies and you have trouble getting the OS going again on another machine.
Pretty sure with Windows it's just a case of throwing the drive in and setting it back up with disk manager (has been a while since I moved a volume to another pc though), really straight forward stuff. Though, as I mentioned, I am backing up about 12TB, if there is a simpler cost effective way for the home environment of doing this I am all ears, not an area I have looked into recently so what am a bit ignorant to current storage alternatives, p.s. don't tell me to get a tape drive
