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.

    I use it as an additional drive on my desk top for gaming. Load times are substantially faster then with my 7200 rpm internal drive. Does not heat up even after a few hours of play.

    Excellent C Connector to USB Transfer . Good transfer speed from my note 8 to my computer. Should have if you need to free up lots of data on phone or transfer the data to computer.

    I added 3 of these in the USB ports on a raspberry pi to make a RAID array for storing movies for a Kodi-based pi system for our RV - it works great!

    If only they could make USB Type C drives that size..but then that would be crazy as it'd get lost. Infact, these things are too small already, lost one as it is. But more importantly I've bought many of these small drives and i use them for storing games and other media especially from Steam. And yes, you can run steam games directly off these as a quick SSD like drive for load times in certain games (Final Fantasy XV is really fast on it) The only downside is the odd write speeds. it always fluctuates in a weird way however the end result is it consistently writing to the drive with little issue as an end result.

    The speed is great - I haven't done a bench test on it, but I know that when I am using it and copying files that it performs much better than the previous USB drive that I had.

    I own a few of this type of flash drive. The older ones tend to get hot to the touch but the 3.1 seems to have eliminated this issue. Very satisfied.

    Nice work, San Disk. Needed a high capacity drive for migrating competition videos, and this fit the bill. Solid value, especially if you got it on sale as I did!

    I forget it's there.

    This is one of those things where you forget it's even there if it's doing what it's supposed to do. We have a very simple file share setup on the USB of our router for things that don't need to go to cloud storage, but that we want to share between the computers in the house/office. We had an external USB hard drive attached for a while, but it started acting up. Replaced it with this a couple weeks ago and haven't noticed it, so that means it's working perfectly. It doesn't store as much as the old hard drive (2TB), but for what we really need, 128GB is way more than enough.
