That’s awesome you have a server for ripping. I made a dedicated machine using my old desktop.
Ryzen 1700, 16gb ram, 12 dvd / Blu-ray drives (one drive does 4k Blu-ray’s) and 2 more usb Blu-ray drives on top.
I ripped so many thousands of DVDs that my neighbor gave me after he passed away.
I did do custom firmware for the internal drive for 4k ripping, but didn’t find the right firmware for the external ones (years ago). Maybe I can find it again once we unpack our storage. We are moving to another state now. Thanks for the info!
