Portable storage is not going to have to worry about Moore's law because memristor is going to ensure continued increases in capacities. Applications might be two years away but Flash will stick around until then.
IEEE Spectrum has a good article about it:

As smaller and smaller circuit components are built out of fewer and fewer atoms, there is one potential way to extend Moore's Law a bit further: use smaller atoms.

Replace the electrons in an atom with muons, and the orbitals become smaller, so the resulting “atoms” take up less space.

Chemistry might be a bit different, though. Also muons decay with a half-life of a couple of microseconds. Though it'll probably be time to upgrade to the next model by then. :)

What I want to know is what happens in about 5 or so years when the companies start hitting sizes where the positions of individual atoms matter. Assuming Moore's Law(I'm using the term VERY loosely here) is 9 months for SSDs and 12 months for hard drives, SSDs will really start to shine in about 10 years. But long before that imaginary point comes, they're either going to have to come up with a new way to store bits or things are going to come to a grinding halt.

To hell with flash! Where is the non-volatile RAM we were promised years ago? Where is the updated version of my old core memory?

Sorry SOBs are so greedy, cramming memory guaranteed to fail down our throats while proclaming it a major breakthrough! What a scam!

"standard" SLC: 100.000 write cycles
MLC: 10.000 write cycles

unfortunatly SLC will not get cheaper because MLC is cheap and popular
(same as with VA/IPS panels and the cheap and popular TN).
