Again, personally i would not go with Optical media (DVD, BLU-RAY).
Yes, hard-drives fail at times, but the ratio of a hard-drive failing
is far less to occur than your DVD, Bluray getting corrupt or unreadable.
Too much in my past, i save my media on Discs, and in a year or two of
proper storage, only to find most of them unreadable or unable to extract
the contents from them.
Storing them on several of my old external Hard-drives and dusting them
off after a year or two, everything is nice and intact, not to mention the
numerous amount of Discs i would have to use to store the many Gigabytes
of media that i have….. Hell No!
