"There are times when you need to transport some small files from one place to another. A flash drive is perfect for these scenarios.
I have used a number of USB flash drives, and have found them to be a lifesaver in many situations. I always keep one of these drives on me whenever I'm at a client site, just in case they don't have a CD drive, CD burner, or, *gasp* a simple floppy. There have been rare cases where the network is down, or not working properly, and copying 5MB on a flash drive is faster than burning it on a CDRW.
Last year we got a chance to look at Crucial's Gizmo! 128MB flash drive, and today we'll be looking at their Gizmo! 256MB USB flash drive. Other than the extra ram, are there any other improvements? Let's find out."
