Yes, it's about the best size to use in a standard USB 2.0 2.5" caddy. Put a large number of MP3s on it, format it as FAT32 and use it in your Blue & Me equipped Fiat car (maybe other modern cars use Blue & Me too). Much larger than this and you have to wait an eternity while Blue & Me builds it's library. Remember to leave some room for "ECO:Drive" data.
