i currently have a 128 gb USB memory stick which j i transfer short and long vids and photos JPEG etc and other formats MP4 etc via PC through the internet okay so far. ? Now i read about a 982 Gb flash drive with USB at £25 why should i buy this 982gb flasg drive rather than my faithful USB stick 128 gb What is the difference between these two devices ? confused. ( SD and mini SD cards i understand but these two ?
