One interesting thing to watch will be to see what happens to SSD pricing as IC density increases. It's probably going to parallel the trends of RAM pricing/density and HDD pricing/density. I don't have any clever or secret knowledge, I'm just speculating based on how RAM and HDD pricing has gone in the past.
Look at HDDs for example. For years, there's been a primary point around $100, give or take 15% - 20%. I remember buying an 80GB HDD for about $120 and thinking what a good deal it was. Now, 80GB HDDs still cost about $40 or so. But, for that same $100 you can buy 1TB to 2TB HDD.
There is a basic cost point for SSDs. The casing, the controller, and the PCB will always cost roughly the same amount of money. SSDs will probably hover at or near a similar fixed minimum price point just like everything else. The extreme dip in RAM pricing a year or 2 ago was an anomoly that I doubt we'll ever see again. Parts of the semiconductor industry almost put itself out of business and they will not likely let that happen again.
I suspect that the semiconductor manufacturers are going to keep their pricing fairly steady on NAND without a lot of major fluctuations. So, I would say don't expect a 32GB or 40GB SSD for $40 any time soon. If you do it will likely be older gen, closeouts, etc but they won't be available in any meaningful quantities.
Again, just my speculation.
