The Toshiba TransMemory U365 256GB is a lightweight USB flash drive that you can easily take with you. Slide the connector inwards before you put the USB flash drive in your pocket, so the USB port won't get damaged when you take it with you. Use the key ring to attach the USB flash drive to your key chain, and you'll always have your music collection with you in the car, or your favorite movies and series wherever you go. With a maximum write speed of 120MB/s, you can transfer an hour-long HD video in about 8 seconds. Reading files is even faster, at a rate of 150MB/s.
