One advantage of optical disks, though I haven't used them in ages, is
the fact that the price of Hard Disk Drives have gone up due to the
real cost of manufacturing them, by including externalities, and
theoretically & practically speaking, it'd be technically "greener" if
storage were made on thin, plastic or bioplastic disks rather than on
metals that use lots of expensive elements and energy intensive CNC
processes. The trend for disks seems to be that there'll be a
successor to blu-ray, as DVD succeeded compact disks. And, the next-
gen after blu-ray, using a blue-violet laser, will probably be in the
terabyte range (1TB+), which would cost a lot less ($2-5/disk, $10-$20
starting out), weigh a lot less than a 3.5" terabyte (1-2lbs) drive
and cost less than a Solid-state equivalent ($1000/TB) and HDD ($100/
TB). http://www.techspot.com/news/39763-sonys-potential-blu-ray-successor-to-bring-1tb-discs.html
