    I use this flash drive a lot. It's lasted me well over a year, and for a flash drive that is used almost daily, that's impressive. With that being said, while you are getting decent speeds (100mb/s) it's not super fast. It will slow down over time, and it does get hot, but it gets the job done nicely especially for the money.
