It's still the safest way to back up and I hope they hurry up and get higher capacity RW discs asap! I have a 1TB drive that's packed up with all my music on it and it's proving a nightmare to retrieve it all. I manage to back up a bit to disc before I got bored and I usually back up films, but now that HD films are often over 8GB it's not possible anymore.
Portable storage just isn't keeping up with memory needs at the moment. And a 2.5" hard drive isn't very practical to distribute your HD home movies to the family.
I agree to an extent. But there are reasons for the decline of DVD-R other than just limited capacity.
Rewriteable optical media has never been terribly popular. As a result, almost all of the optical disks ever written are of the WORM variety, write once read many. Because of this, most users consider optical media to be less convenient. They were willing to use it when there wasn't a viable alternative. Now that thumb drives and external usb drives are dirt cheap, users have switched to those options for many scenarios that used to be served by DVD+/-R.
While storage requirements are ever growing, it is quite clear that portable media has reached the point where no more storage is needed for a large percentage of computing tasks. Pretty much all types of data and files can easily be stored in bulk on a single thumb drive... with of course the exception, as you pointed out, of video and to some extent, music.
Which begs the question, is video storage in and of itself enough to make the computing industry switch to a new removable media format? My guess is yes, eventually, and it already has to some degree. What hasn't happened is manufacturers bundling the hardware by default. It can still be purchased and/or installed by that small percentage of users that desire the functionality.
Also, you say it is a "nightmare" to retrieve music from a 1TB hard disk. Could you explain that? If anything, hard drive based storage is the most convenient option available.
As for distributing HD home movies to the rest of the family?
Sorry, I couldn't resist chuckling. What percentage of users do you suppose would make use of that functionality if it were available today? My guess would be somewhere between 0.01% and 0.001%.
The only true demand I see for writable blu-rays is for the purpose of video archiving. At this time it doesn't seem that this comprises a terribly large or profitable market. Hence, it makes perfect sense for most computers to be shipping with DVD rather than blu-ray drives.
