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'm a sucker for internal storage so when Best Buy had this 128GB storage device on sale for 26.99, I definitely jumped at it. I've loaded it up with all kinds of movies and TV shows and plugged it into the USB slot on my XBOX One and haven't looked back. Hours of entertainment available immediately in a slim profile and easy to use package. Love it.

    Bought this flash drive so I could take most of my music with me in the car. Amazing how much space is on this. Downloaded over 3,000 songs and I haven’t even dented the memory. About the size of my thumb nail and plugs right into one of my car’s USB ports. Great for long trips or even short trips around town.

    Built a new pc and needed some flash storage for getting pictures and other large files moved to a new drive. Bought this and it didn’t disappoint. It was amazingly fast going on to my new pc when it’s able to utilize the new technology. I highly recommend this drive for fast reliable storage

    This item is worth keeping an eye open for when Best Buy has it on sale. You’d seriously be saving over $100 and the amount of storage included is insane, not only the storage but the convenience of size it’s wouldn’t be easy to loss or misplace due to the fact that can stay attached to any computer or laptop. This is worth every penny.

    Absolutely fantastic USB drive! USB 3.1 standard provides LIGHTNING fast speed, and size is great! Basically no larger than a thumbnail, can be plugged into a side USB port on laptop and not protrude, can't be easily dislodged or knocked out. SanDisk drives are high quality.

    Love this flash drive. I have had at least a dozen and this is the smallest and fastest flash drives I ever used. It is so precious, I keep it in my jewelry box. It is easy to loose so put it somewhere safe when not using it. Will buy another one or two very soon but with a larger capacity.

    Thought it was metal but it wasn’t. The price is pretty great though and the speed is good too. Only thing is the speeds mentioned even though they can get really high you will rarely get that speed due to your device limitation so maybe something cheaper is better for some.

    Has a little lip to make removing a snap. A little change but a genius effect. Cannot complain about the speed and efficiency of this tiny flash drive. Works great with most TVs. Transfer speed is decent enough for any typical use. Very easy to lose, take advantage of the tab and put a flag on this device. Ha

    Large volume flash drive in a compact size. Using this flash drive to play music that I have stored on this flash drive since my new car does not have a CD player. Fits easily in my car USB ports which are limited in clearance in my console.

    Extra Storage for Nvidia Shield TV

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

    I had recently purchased an Nvidia Shield TV and was trying to run a Plex Server on it. Unfortunately the performance was a bit lacking and after doing some research I figured that I should supplement the 16GB that comes with the standard Shield TV with some external flash. The boards also suggested making sure that I stick with specific models of flash and I settled on the SanDisk Ultra product. Since adding the extra memory I'm happy to report that the performance of the Nvidia Shield is much better. I have a home NAS that is where all the content is being saved so I'm not using the flash drive for that purpose. I like that this product is very small so I don't have anything noticeable sticking out of the back of the Shield TV.

    I love this drive for the form factor and speeds. This is the type of drive you can leave in a laptop and throw in a backpack. The capacity aspect also allows you to expand storage by a considerable amount without having a bulky hard drive dangling off the edge of the table.

    This is a great drive. Found a good deal and needed some more larger drives. This drive delivered on speed and I like the small profile. Great for spaces like in laptops, the car where having a long drive sticking out is a pain. Still going strong with lots of use.

    I wanted a bigger thumb drive and something compact. My 1st thumb drive I broke as my knee hit it and it snapped off. This one is perfect. Very compact and holds a lot. Be warned, it gets warm. Also, I don't like that it comes with all this software on it. I wanted for storage. I ended up copying that elsewhere and reformatting this. 114GB usable.

    I was immensely surprised when I saw this San Disk 128GB 3.1 Flash Drive that is snug enough to use on my PC that sits under my desk. My problem in the past has been to move my foot and accidentally catch the flash drive sticking out and bend it or break it. Not any more. Plus the price was really low for this 128GB of a drive.
