Customer Ratings & Reviews

The 3.1 version is extremely fast. I use it for my Linux OS disk. Extremely nice, compact and convenient. I would recommend this to anyone that wants large storage and fast speeds. I'm very happy with this purchase

This is my 4th purchase of this product. Its fast and efficient although, I wish it were not made of all plastic. Worried about it heating up and melting. But other than that, I am very pleased with it.

I replaced an older 16B USB thumb drive with this SanDisk UltraFit 128GB USB 3.1 thumb drive. and love it. It is small in physical size, much larger with 128GB, and much faster. Love it.

The tiny size is a plus for me. The speedy transfer and large capacity are as advertised.

I have been very surprised by this tiny drive! Very easy to use and format. Has great amount of space and I hardly even notice it on my key chain. Love this product

This flash drive is very compact, I use it to transfer files from computer to computer, flash drive does not stick out more than 3/8" from the computer.

Great usb drive with massive amount of storage. What’s great is how small it is. Great for expansion storage for small spaces because it doesn’t stick out far from the device. Fast as well

It works great and I really like the compact size. The size is good for using in vehicles to play music.

I love the SanDisk Ultra Fit(TM) 128GB USB 3.1 Flash Drive. It features the latest USB 3.1 standard and is perfect for storing files on the go. I love to use these drives for saving mp3 for playback in my car on my 35-45 minute commute to and from work. These drives are reliable, shock-resistant, and don't heat up as much as previous models which could get hot to the touch. These are perfect for vehicles with USB drives given the very low profile which means they won't get accidentally knocked with resulting damage to the USB connection. Purchased two of these and got a great deal as usual from Best Buy.

Very compact , convenient and easy to use. If needed i will buy it again

The SanDisk Ultra 128GB is a reliable and high-speed microSD card, perfect for expanding storage on smartphones, tablets, and cameras. With fast read speeds up to 120MB/s, it handles HD video, apps, and large files with ease. Durable and affordable, it's a great value for everyday use. Ideal for those needing extra space without compromising performance.

The SanDisk Ultra Fil 128Gb USB 3.1 Flash Drive can read and write data at maximum speeds allowed through USB 3.1 technology. The small form factor is great for tight spaces like laptops. The only downside is that the device will get hot quickly when transferring lots of data.

This memory card is a nice capacity. It is very compact which is nice when plugging it into a computer. It does get a bit warm if you are using it a lot but nothing too bad.

The SanDisk 128GB USB 3.1 Flash drive is extremely small for places you don't want it to stick out, fast (read and write), and doesn't seem to get as hot as the previous model.

Bought this at a great price on sale, ton of storage and transfers well, and pretty fast too. It is small but be a good human and don't lose it!, LOL. I recommend this.

This is a very practical device; it's physical size is small enough to leave attached to a laptop to avoid losing it. It has enough room for tons of data and is pretty fast.

Very small, and handy. easy to use. Compact stores a lot of music.

Very small and fast, it does gets a little hot but nothing really bad. It is being in use for some time now and no problems so far.

Small and tons of storage. Needed something for my FireTV and this fits the bill. It's quick also!

The speed in this little stick is incredible if you have a USB 3.0 or 3.1 slot to use with it. Even on USB 2.0 slots it still felt quicker than my other drives. I have no benchmarks to prove it, but that was my impression anyway. Still blows me away that so much storage space can be stuffed into such a small little flash drive. Downside is that if you have it full and it crashes or gets lost, that’s a lot of data to lose. Just a heads up to users that these devices should be considered temporary storage only for this reason. Keep backups on another device whenever possible!
