Solid State Drives and upcoming technology like 4k

   I am actually pretty excited about 4k technology in terms of image processing.  One because an increased standard with respect to imaging, means that more and more video in the future will look like something of the spectacular still photo imaging that I am seeing.  The big hurdles, however, for such technology that I've seen so far are given much not only only to graphics cards, or display monitor issues coupled with decent screen refresh rates to make motion imaging worthwhile, but that something as simple as the hard drive isn't posing a bottle neck to data transfers.  I've actually tried to run something like 4k video on a non 4k ready laptop, for instance, and found that my older type kinetic based 5200 rpm hard drive really had much latency (really almost impossible playing the video, 2k was a little better) when even attempting the higher data overheads, and this not withstanding any data bottle neck through say my now 'non high speed once classified as high speed broadband' provider.  Likely it seems potentially that having higher speed processors could aid, but really prior to smaller devices, like tablets and smartphones catching up to speed, and I imagine this may not be for another few years, upgrading say the desktop might include a new solid state drive (as opposed to old fashioned kinetic drives with a maximum platter speed of something like 7200 rpm), the solid state drives are running well in the order of several hundreds of megabytes per second on any given average transfer.  My personal experience with imagining technology are that solid state drive are worthwhile, especially when data files even for a still image (using at or above 16 bits per channel rgba increases data requirement significantly, while online images displayed to the public might be typically well under 20 mb, processing on the other hand increases this several times an original amount, and that's assuming you weren't processing in a raw format), images load in a snap for more intense data handling needs, and processing goes way faster.  On the other hand a laptop of mine at several years old now, trods along measuring data transfer rates that really are lackluster, and in fact, in some cases less than way back when ultra dma was the in thing, technically running at something like at some several megabytes per second which is abysmal, and makes for much slower image processing.  Likely unless the kinetic hard drive manufacturers are able increase data transfer rates through some technology break through, really the future is in solid state drives, and I'd recommend one as a big upgrade starter for any desktop or laptop if possible, and the prices on these drives are coming down significantly.
