    I have used Sandisk exclusively for years. I had one go bad a few years ago and Sandisk replaced it without a hassle. If you are still using USB 2.0 devices, the 10X speed increase in 3.0 is great. Watch for sale prices they can save a lot.

    These little USB flash drives are my go-to drives. Retractability is key. Hate the capped ones where I always lose the caps. Can't believe the capacity you can get these days!

    I needed to transfer a load of pics and vids to someone, and it was just too much to download. Handing him this 128 GB thumb was the answer to the question of how to do it most easily. And the price was great too.

    Purchased a 128 GB San Disk Ultra USB 3.0 Flash Drive to store pictures. Speed is awesome! Drive was on sale but out-of-stock in our local store. Store management helped me order on line and had it delivered to my home at no extra charge. Fantastic service!

    I use this Sandisk 128GB 3.0 USB drive as a video server connected to a HooToo TripMate which acts as a media server. Works fine, holds lots of movies and there is no noticeable delay or buffering so I'm happy. No complaints, works great for my purpose.
