    I use this on the back of an iMac for time machine backups. Its small so it stays out of the way and doesn't get hit when reaching back to add/remove other USB devices. Since I only use it for backups, I can't speak to peak or sustained write speeds.

    I love these. I have used many and not run into any problems. I have not bothered to speed check them against other drives, but they are plenty fast for my needs. i mostly use them for automatic backups (syncs) in laptops. I can leave on of these plugged in and the usesr does not break them off, remove them, etc., like with a full size drive.

    Expanded memory

    I bought this USB 3.1 flash drive to expand the memory in my Nvidia Shield. I was drawn to the compact size-- there is nothing sticking out the back of the box that something could get caught on or have it be pulled out accidentally. It was recognized immediately by the Shield and I had no issues installing it. So far it has worked great.

    This SanDisk Ultra Fit 128GB USB 3.1 Flash Drive is perfect for putting all my MP4's on for listening in my vehicles. While in my vehicle it has a low profile and is hard to see from outside my cars, which adds a safety feature from possible theft.

    SanDisk makes a great little thunb drive. I wish it were 3.2. But, 3.1 gets the job done, too.

    Bought this for the secuirty system on my wife's new car. It had to be reformatted to a different format, which I was able to do with no problems, even though the instructions told me that I might have some. it works as advertised, the small size is perfect to be able to keep it out of the way.

    It's so small and helpful! I plugged it into my nvidia shield 2nd gen for additional system storage. Its really fast when I'm transferring files. It was a huge upgrade from a slow bulky usb 2.0 adapter and SD card.

    This product has done everything I've asked of it. If you constantly need to take it in-and-out of the port, it's a bit of a challenge as compared to a larger unit, but that's a small price you pay for something that takes up no space and is barely visible. A+

    My review may be limited: I purchased this USB drive for music storage for playback in my car. It has not been used for repeated file transfers. However, it reads quickly and have had zero issues with it being a permanent device in my car.

    Great little drive if you can find it on sale, the build is good and I like the stealthy looks. Cons, is it does get hot when transferring lots of files, I guess this probably can't be help due to it's small size. I haven't seen the advertised speeds yet but it is definitely quicker than my 2.0 drives. I'm replacing all my slower 2.0 smaller capacity drives with 3.0 or 3.1 drives and larger capacities. This is a pretty decent drive to get, although don't pay full price for it, wait for a sale and get them.
