If you made them yourself they are basically irreplaceable and RAID will replicate any bitrot to the other copy undetected.
Even if not, they still represent a great deal of time to accumulate and then to replace. Most of mine have been recorded* from Cable TV programs, and replacing them would require either waiting a huge amount of time for all of them to be re-broadcast (if ever), or else purchasing literally thousands of Blu-Ray disks.
Again, I cannot possily reiterate that RAID is #NOT# a backup solution. On several separate occasions I have lost an entire RAID array. Each involved a completely different type of failure. In two cases I was able to manually recover the arrays with only minimal loss of data. In one, no data recovery at all was possible (a Windows system). In every other case I had to resort to backup. One of those times, it was the backup system which failed, and then DAR really saved my butt, as it has done on a number of occasions when the corruption was far less extensive.
