i asked earlier abuot getting a 500GB external hard drive to my full & slow computer. I do a lot of ?

I do alot - aloy add photogrophy so I have hundreds of patterns and templates and keep my correspondence and of course my journal entries that are made daily, even if they don't have too. So now would I be better with several 8GB flash drives and keep different Seasons, people, etc. Would that be a good fit? Are is the external hard drive great for my storage. Hurry the 5:OO starts soon.
