Recently, Sony announced that they were killing the 3.5-inch floppy disk. Which is fine, as far as we’re concerned. Macs haven’t used floppy disks in well over a decade, and with the internet, who needs ’em? But sometimes you just need to move files from point A to point B with a minimum of fuss, which is where the USB flash drive comes in. Plug it into your Mac, copy some files, plug it into another Mac--boom! File transfer done. While we usually use flash drives to move images, Word docs, and maybe a few ripped MP3s between machines, Kingston’s new Data Traveler 310 is made to carry a lot more--256 gigabytes, to be exact.
