I recently bought a 16 gigabyte sandisk pen drive.It is one of the best company for pen drives.The pen drives work great and are really worth it.These pen drives are really durable cause once I forgot my pen drive in pant and my mother put my jeans pant in washing machine.I thought that it will not work but to my surprise it was working without any issue even all my data on that pen drive was there. Even its write speed is good.I will recommend this pen drives to everyone out there because it is worth it.
