    I have only used 2.0 USB flash drives before so this was a venture into new territory. I also will only use Sandisk Flash Drives. They are very well made and work very well for a long period of time. This particular USB Flash Drive was discounted so much at my local store I had to pick it up. It is SO MUCH FASTER than the 2.0 one is. It is putting my 2.0 to shame. If you want to get a 3.0 flash drive, you can do NO WRONG getting this product.
