I am trying to figure out what is the best media to make backups of my old games for old consoles like the Sega CD, PC-engine, Saturn,
not to mention other weak-laser 5th generation consoles like the Amiga CD32, 3DO, etc.)

When I look it up on forums, I read stuff like "use 4x 650MB media" but when I look it up the only 4x 650MB media is CD-RW.

Does anyone know what is the best brand for this sort of backups?

Is it more important to use 650MB media or is it more important to use 4x, or to use high-reflectivity that isn't either 4X or 650MB? Does it make a difference if its CD-R or CD+R? Any specific brands?

I just want to use the best for my old games.

Thanks for any suggestion?

I use these for my Sega-CD and they always work great.
