The prices for memory is falling, with 64GB USB stick in around $20-$25 range and a bunch of PC blogs and news sites "promising" 8TB-20TB HDDs in the near future. Other "sources" say that USB-type of memory chips [I just call them memory rectangles] that goes into SSDs will match per-GB cost of HDDs sometime in 2017. I think that in 2015 manufacturers will most likely release a 6GB HDD and probably an 8GB HDD next year. Just couple of year ago porn used to be like 8MBs per zip file, now 350MB+ zips of porn are frequent. [Know what I'm sayin'?!]
