Customers are saying

Customers consistently note the Ultra 64GB USB 3.0 Flash Drive's ample storage capacity, ease of use, and competitive price as significant advantages. Many appreciate its fast transfer speeds thanks to the USB 3.0 interface and convenient size. While some users mentioned the drive can get warm during extensive use, and a few expressed concerns about the design of the retractable case, the positive feedback on storage, speed, and value outweighs these drawbacks. The bright color is also frequently praised for easy identification.

    Sandisk has always been the name for USB flash rives and this one doesn't disappoint. Super flash with a retractable switch to easily put in pocket without damaging the drive.

    USB 3 is very fast and if you have a USB 3 port you need a matching flash drive. This one works well is feels solid. I like the retractable feature, no cap to lose.

    This SanDisk Flash Drive works perfectly, and I hope their USB thumb drives never end. They are the best way I can transfer my Mac files to my PC partner, or get one of her files for CMYK printing.

  • Not compatible with Windows 10

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I was so excited that this was on sale during Black Friday, especially since the reviews looked good. Finally received it in the mail, but I ended up being very disappointed. It works with Windows 10, but the security feature is not compatible with Windows 10. I even updated the security feature, but it still didn't work. It took about 18 minutes to transfer 22 GB onto the flash drive which felt kind of slow to me. If you need the security feature and are running on Windows 10 then I wouldn't recommend it, but if that doesn't matter then it will work fine for you.

    No, I would not recommend this to a friend
