Falsh drives certainly do the job and are the most portable. Also, they are the easiest to lose or misplace and tend to be viewed as a temporary storage medium rather than a permanent one. So if Marcus wishes to take his files with him, a flash makes sense and are nice to have around. But for more permanent back-ups, I personally prefer a true external drive. The beautiful thing about this adventure called faith is that we can count on Him (God) to never lead us astray. Charles Swindoll
