The SanDisk Cruzer is the world's first portable, pocket-size storage device with upgradeable flash memory. Its stylish, compact design can be slipped into a pocket or purse for easy transport of personal computer data files, image files, video and audio between homes, offices or any other location where one would want to transfer personal files and information.??The Cruzer fills a void in the portable storage market that neither floppy disks nor CDs can address. The all-in-one unit plugs directly into the industry-standard USB port that is built into desktop PCs and without any additional components necessary. It's powered right from the USB port! The Cruzer is created for today's active, on-the-go lifestyle.
