Hi, My pc is about 3 years old and so is a little ont he slow side for editing etc although it works its a bit slow. I am hoping to get a laptop for use in the next year or so so dont want to upgrade my desk pc as it will not be worth it but someone has suggested that if i get an external hd this could also be used on a laptop. I dont know about these things at all so is this true and if so are there things to bear in mind for my old desktop and future laptop. I know that if it works i will still be stuck with my old processor (slow!) so may not make much diff speed wise but just for storage? Any thoughts on this would be welcome.
