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.

    Barely Better than a USB 2.0 Drive

    PHYSICAL PROPERTIES: I was looking for a small drive to replace my Verbatim Micro USB drive, which is an ultra small drive that fits in my wallet pocket. The SanDisk Ultra Fit, while approximately the same width and length, is over 3x as thick (full height USB). I may see if I can take the drive apart and isolate just the flash chip to make it more portable, although it looks like this may be more difficult than on other drives I've had due to its construction. The drive has a 1-sided grip, which may be a problem for removing the device (for instance, my monitor USB port has a lip on it, and the grip tucks under that, so I can only pull the drive out by the sides, which is quite difficult. If I'm able to take it apart, I should be able to get a much better grip on it. The drive is all plastic and feels pretty cheap. READ/WRITE SPEEDS: My tests were done on Windows 10 PC with a high-end SSD using a USB 3 port. I left it in the default exFAT. When sequentially reading mixed files, I get about 80 MB/s. When sequentially writing large files (500 MB+ per file), it very briefly started at about 55 MB/s then quickly dropped to 30 MB/s. After copying about 10 GB, it dropped to 16-20 MB/s before finally dipping to about 5 MB/s in the last 5 GB. Keep in mind there weren't any files on the drive yet and all files were copied at once, so the lag in the last 5 GB doesn't make a lot of sense. When sequentially writing small files (KB to a few MB), it is no faster than a USB 2.0 drive, averaging around 1 MB/s write speed. INTERFERENCE: I've never had a USB 3 drive cause interference with my Logitech mouse wireless transmitter, but this one does for some reason. It causes the mouse cursor to lag and jump around the screen. I've put an extender on the mouse transmitter and so far that seems to work, although I haven't tested it extensively. TAKE-AWAY: It doesn't perform much better than the Verbatim drive it replaces, but it does have a lot more storage, which I needed. And it's cheap. If I can take it apart okay, it will be worth the upgrade, although I'd much prefer to pay more for a quallity half-height USB 3 drive that performed well, but they don't seem to exist.
