Well if size is important to you and you like, want, or need a ton of storage than the Migo 1GB Smart USB Flash Thumb Drive is the way to go. The design of this small flash drive is one of the best. It is super small with a ring on top for a key chain or any other attatching items. Migo isn't a huge name in data storage but the performance of their flash cards aren't bad. The max size so far is 1GB for these designs. geekBlue gave them 3Gs because of their steep price but says to look around because somewhere it's always cheaper. A 1GB card will run you $340, where a 512MB is a lower $230. You can go for a smaller size for less money but if you are looking for a cheaper flash drive to use as a "floppy" then try looking at the PNY models.
