Flash drives can now store about 32gig for about $30. A one gig flash drive should be under $5 during a Christmas sale and may almost be a 'throw-in'. They are very handy for file transfers between computers or for 'pocket carry'. For backup or longer term storage, you might consider a portable hard drive. They are available from about 250gig to 1terrabite and cost from $50 to $100. They are Blackberry size and use the same USB port. Depending on the size of your pictures, a flash drive can fill up very quickly. My camera setting per picture is from 250K to 1 meg. At 1 meg per picture (high resolution) that would mean 1000 pictures on a 1 gig flash drive. You can always save the pictures at a lower resolution by using a photo editor in your computer. For snap shots 250K resolution is more than enough. So using non-fuzzy math, a 1terrabite portable hard drive could store about one million high resolution pictures. If you move into video, you will need lots of storage space. Both a portable hard drive and a flash drive suck power from your computer, so plugging in a laptop for mass file transfers, should be considered. Hope this helps a little. Good luck!
