I can't remember which one it was that is already slated to consume 18 GiB of space. I'd say we'll hit 25 within a year from now.


Hard drives have a base cost (cost of the platters, general circuitry, casing, heads, etc.) and once you get beyond that base cost, you're paying for precision and therefore density. That's why hard drives of enormous capacity are relatively cheap and usually fall in price rather quick when something bigger comes out.

Solid state drives, on the other hand, have an increased cost in production with increased density. Right now, the density is increasing faster than Moore's Law dictates it shrinks. The result is extremely high prices due to high cost of manufacturing and improvements to process aren't keeping up. Simply put, I can't see a 1 TiB drive becoming affordable for a very long time (at least for sure until dies shrink a lot). SSD is certainly an improvement on long term storage from HDD but, I can't see the technology ever replacing their old metal bretheran. We'll need something that sticks to Moore's Law for that to happen.
