SSD's may be the next big thing but they are only a replacement for a spinning hard drive, using current technology. The storage medium has size limitations. The reliability may be better eventually due to lack of moving parts but the size per Gb probably won't be and speed won't be (I didn't particularly mention speed in my original drone) and power consumption is a problem. My point (I think) was that we need to refine the horse that we have while we wait for the motor car to come along.
