Which 50GB BD-R discs are the best for these? Or does it matter?
You always want HTL Blu-Ray discs. DO NOT GET “LTH” discs.
Sometimes you have to research if a certain disc is HTL as they don’t always advertise it.
But from my research, it seems the best discs come out of Japan. And apparently most discs are NOT made in Japan. I believe people at one time were saying Panasonic BD-R discs made in Japan were the best. But they seem hard to find and are expensive.
But I would suggestion looking at Verbatim DataLifePlus discs. As those discs should be higher quality i.e. less coasters, has a hard coating, and the data on the disc should survive longer i.e. it’s archival quality. Apparently data on discs can develop disc rot.
Another to look at are Digistor. I believe they only have one line of discs compared to Verbatim. They are HTL, hard disc coating, and are made in Japan. I bought a stack of 25GB and 50GB discs to use for my Star Wars Harmy burns, and also as an extra backup to burn all of my data files to. As even with external hard drives and flash memory to back up your data, those still have a risk of getting corrupted via a virus. Also burning every so often a copy of all of your computer files to a Blu-Ray disc will just give you an additional protection layer against data loss.
