I wouldn't expect there's much of a difference in how laymen (jurors) understand reading out and using an image of a hard drive and reading out and using an image of a flash device.
First of all, for most of them, it's black magic. For the few who know a bit more, will be convinced by arguments of analogy (after all, nowadays many hard drives are in fact flash devices, and the details of interface protocol are beyond what jurors will care about).
