1 year ago on Why Has Flash Storage In Mobile Devices Plateaued?
So my rebuttal to aelfwyne is that according to this website( http://www.theregister.co.uk/2012/02/21/nand_bleak_future/ ) flash memory has a diminishing returns type of design. It quotes a study saying "While flash density in terms of bits/mm2 and feature size scaling continues to increase rapidly, all other figures of merit for flash – performance, program/erase endurance, energy efficiency, and data retention time – decline steeply as density rises." So as flash gets more capacity it fails more often, much more often, it goes on to say that if you increase latency time by 4x you would reduce lifetime by 10X-20X while also shrinking the density of the memory. It also goes onto talk about how we are to a point where it is more economical and easier to use disk drives than flash for storage above what we currently have because of the size and reliability issues involved.
Also a MAJOR POINT is that the flash in your phone is not the same as the flash in a thumb drive or a SD card etc. it is integrated on the "system on a chip" (SOC) where it is much much smaller than the flash you see on store shelves making it more expensive and harder to expand given the same difficulties as mentioned above. Wiki has a picture of the (SOC) and shows a diagram of how small it is in relation to the chip and why it is so expensive to double the size and with the failure rates of flash at the upper ends having your cell phone wiped clean every couple months is not really and option for most cell phone users. This has nothing to do with a conspiracy by the big phone companies to defraud you some how. Its a technical matter that it is hard to expand flash memory economically and with any amount of reliability. Many people are talking about the end to flash memory and how it will have to be replaced by a different technology soon.
