16GB Pack of 10 at this price and I was a bit skeptical. These drives are well made and look and feel high quality, not cheap. It's harder to say internally, so I can only say from my experience. I've used a few out of the box and haven't had any issues so far. Remember this is USB 2.0 so they will be slower if you are used to 3.0 speed but if you don't need the speed then why pay more for the extra speed?
