What happens when your hard drive chashes?
That's what backups and restores are for. ITs' important to not overlook that because eventually every hard drive will fail. Keeping the CDs is another safeguard but ripping thousands a second time is not a desired use of time. So unless you want to be forced to go back to a CD player at some point, have that backup and restore solution in place. OR at that point punt and go mostly with streaming from services like qobuz, etc.
