FWIW the rw's I have and that continue to work, are Sony DVD+RW, well
over 5 years old now. I understand there is a DVD-RW but I've no
experience with them. Today my objection is the size. In comparison to
a system driving 3d printers with gcode from Cura-5.4 that is not rolled
up into subroutine loops, I have some of the more complex and large
parts part files that will not fit on a dvd. So it simply impractical
for me to back up to a measly 4.7Gig dvd.
That's why they invented Blu-ray:

25 GB (single-layer)
50, 66 GB (dual-layer)
100, 128 GB (BDXL)
(Up to four layers are possible in a standard form BD)
