RAID setup not "safe"
I have been saving my photos to 2 500gb drives which mirror each other (RAID1).
I was led to believe that if one drive fails, I just replace it and all is fine, however a post on another thread led me to believe that this is not the case.
Am I wrongly concerned?
(I do additional backups of the RAID drives as well on other external drives on about a monthly basis.)
