Will probably die out before it sees any consumer products.
Flash drives are just too easy to use.

I wonder how the longevity of the data will be. Starting to find a lot of my old CDs and DVDs are unreadable. Granted, I probably didn't follow best practices in storing them.
They might store better if you used a desiccant and put the CD's in a more controlled environment like we guitarists do with guitars, inside the case there is an accessory that slowly gives off moisture to keep the wood from getting too dry which causes cracks. You could have them in a case with just the opposite, a desiccant to keep the moisture down.
I think the best way to preserve digital data is to have it in several formats, like thumb drives, CD's, hard drives and the like, so you have a backup in completely different technologies.
For instance, you could put ones and zero's onto papyrus🙂

For pure archiving solid state type technologies will kill off any 'new' tech R&D in the disc industry. SSDs are what the consumers want, so the innovation and money is there.
Discs are dead, no matter much data you can burn on it.

and who can bother with optical discs anyway? they're so impractical. waste space and you actually need to manually put discs into a player etc... screw that. they were okay while there wasn't an alternative, but now they're history.

This is not stricly on topic, but while we're talking about flash-type memory:
The instant on PC is very close!

the big ones are still too expensive for my storage needs, but I'll start replacing my storage drives as soon as it becomes feasible in the terabyte range. maybe 1-2 years from now I think, the prices are falling fast.

The developments at Samsung though, are looking at nanosecond access time and trillion write cycles. 5 years from now, comps will be in a totally different ballgame for sure. Then, the biggest question will be: Are they waterproof?

but the thing with real life is, you're not gonna saturate that in any normal usage anytime soon. the files you write frequently, are VERY small. while the big files are very infrequent. it takes a lot of time to fill up a 100+ gb drive, no matter what you do. for an average movie/music user months or years. and that's just 1 write down, 4999 to go.
and the reads are unlimited. so when you store that big ol' chunk of porn on the ssd, it's gonna stay there for as long as you the ssd fills up. you can watch it a trillion times if you want, and it's still gonna be that 1 first write with 4999 to go.
generally the big things you store, like movies etc, you're basically storing them 'for good'. it's most likely gonna take a LONG time before you delete it, if ever, and start the #2 write over that space.
you're not gonna run out of writes, not in the real world.
