Very cool archival setup! Funny you say that about Verbatim. I have a several old burned discs from the 2000s and 2010s where the dye has degraded and is no longer readable, but I have one specific blue Verbatim disc my childhood friend burned for me in the late 90s, and it still reads today!

Exactly my experience. Verbatim is worth the additional cost in my opinion. I mainly do the archival as a hobby... not sure I ever gonna need it :-) However, I'm pretty scared of ransomware these days, so I tried to make my setup as ransomware proof as possible and zfs-auto-snapshot + self burned blurays with the most important data seemed like a good idea :-)
However, I never use anything but Verbatim, never had a bad experience with it.
