DVD-RAM or no DVD-RAM

is it good to have or not?

what is the best drive? looking at the H22N but does it only come in black?

RAM is good if you want a reliable , removable backup. It’s just so much better than using CD/DVD RW media.

DVD-RAM is better than DVD+RW or DVD-RW if you want a rewriteable medium. However, DVD-RAM is harder to find and quite a bit more expensive. I have yet to see any of the 12x DVD-RAM for sale anywhere that I shop.
