[QUOTE="cwa107, post: 1106343, member: 24098"] Not sure that a RAID1 setup is what you actually want. It's just not intended to be used in this manner. It's really intended for always-on servers that have to have redundancy in the event a mechanism fails. Constantly breaking the RAID set by separating the second disk is going to mean constant rebuilds - and with software RAID, that's going to lead to performance problems and potential data integrity issues. I'm not sure what lead you to the conclusion that RAID1 was the right solution given your circumstances, but I would recommend simply using Time Machine with your external. Each time you plug it in, it will automatically backup everything that has changed on your system. And if you happen to leave it plugged in and are working on your Mac, it will instantly backup any changes that are made. If there's a failure, you can easily recover from it with very little hassle.
