Even as devices get smaller and thinner, one of the things keeping them from getting too small or thin are the components inside. For example, memory. Despite the fact hard drives (HD) and solid state drives (SSD) are already pretty small, we need them to get smaller if we want even smaller gadgets and toys. We just didn't expect it to get this small. SanDisk has officially unveiled their new 64GB SSD, which is smaller than a postage stamp.
