Customers are saying

Customers frequently mention the Ultra Fit 128GB USB 3.1 Flash Drive's small size, ample storage, and fast transfer speeds as major advantages. The drive is also praised for its overall performance, ease of use, and large capacity. However, some customers have noted that the drive can overheat, and a few have expressed concerns about the plastic case material and its easily lost form factor.

    Cheap and simple to add extra space on my Mac without having to buy a whole new drive. Storing all the movies on it so it doesn't fill up the drive.

    This is a very tiny storage device. It can get hot if you transfer a lot of files to/from it, since it doesn't have much room for thermal radiators or anything. So just wait a minute after your transfer is done before touching it. I wish it had come with a small lanyard or keychain or something.

    I got this thumb drive to replace another drive that I store music on in my car. When plugged into my car's infotainment system, it doesn't stick out, less of a chance to get hit and broken.

    purchased this on sale. I can say the size capacity for the price paid is fine, and the red speeds are tremendous, but the write speeds, I expected more when I found out it's write speeds average about 50 MBPS

This USB Drive does not have any published write speeds, however, it should provide you optimal speeds when connected to a USB 3.1 Interface. If you are not getting optimal speeds, you can contact us and we will perform a speed test on your USB Drive to check if it is performing within the expected specifications. We will check if your USB Drive is eligible for a possible replacement. I would suggest you to please contact SanDisk®️ support at www.sandisk.com/support. We will isolate the issue and will assist you towards a resolution. SanDiskConnections

    Big deal in a small package. This drive is great at its function and even better is it doesn't have a cap that I know I'll always lose. Speeds are definitely good for the everyday user.

    When I get a flash drive I always like to get something big enough so that I do not run out of space in the middle of my projects. SanDisk has always worked great for me.
