    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.

    I have purchased this to use it in my Tesla Model 3 to record videos for DashCam. I used older USB but it was small in size and very small. This was perfect for my need.

    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.

    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

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.

    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.
