More space than I needed - Bought it almost exclusively as a Windows 10/11 install flashdrive utility. Only needed maybe 8-16GB but this 64GB was the smallest they had in store at the time and it's was also extremely cheap. My only concern is that it's so small that tim afraid I might eventually lose it. But the small size also addresses a significantly worse problem older long flash drives had, which is flexing and eventually breaking.

Customer reviews
Write a reviewThese are great small physical size drives - I have purchased several of these in 32 and 64 GB sizes for different projects to use a the main drive for DDWRT and OpenWRT networking projects. I love the low profile so they are not in the way!
Small and quick - Great for a small USB. Fast and efficient. Glad I got this before the AI price boom
Love this - Amazing so easy and fast to use. 10/10 I love this
Excellent - very fast and well designed. every penny is worth, very slim design and handy
Great fit for Lenovo laptop - Fits close and just right tight fit to my laptop. Used for Bestcrypt encrypted container for my data.
Compact, Fast, and Extremely Convenient - The SanDisk Ultra Fit 64GB USB 3.1 flash drive is a fantastic little storage device. Its ultra‑compact size makes it perfect for laptops, car stereos, and any setup where you want extra storage without a bulky drive sticking out. Despite its tiny design, it delivers impressive speed — transferring files is quick and smooth, whether you’re moving documents, photos, or videos. It’s reliable, easy to use, and stays cool during transfers. The build feels solid for such a small device, and the 64GB capacity is great for everyday needs. It’s one of those accessories that quietly becomes essential because it works so well and takes up virtually no space. If you’re looking for a fast, discreet, and dependable USB drive, the Ultra Fit is an excellent choice.
Low profile USB - This is a solid product. It sits nice and tight to my car's console so it doesn't get bumped.
Compact USB - I bought this to create install media. 64gb is near the smallest capacity available, but I find sandisk is reliable, and 64 gb in a compact unit is more than adequate for a windows installation media creation.
Small, sleek. - Mine Is 64 Gb. Small and sleek and even had a small hole so you can put it on a thread or something.
Ultra fit flash drive - Ideal for digital picture frames.that has limited space for flash drives,
Small and compact! - Works like a charm! Small and useful. No issues on my end and I would buy it again.

sandisk - The computer guy copied all my stuff from old computer.
Good product - Haven’t used much, but it has been helpful when needed extra storage
Sandisk Review - I use it as a boot drive for my raspberry pi. It runs a local AI model. Great product!
Fast and compact - Works well so far. I use this to store flac music files that I want to listen to in my truck.
It only lasts about 18 months - This is the 2nd Sandisk UltraFit 64GB to fail after 1.5 years. I use it to extend storage on my Sony TV, basically write apps on it that I rarely use, and both drives failed after about 18 months. Yes it's still under warranty but, you have to create an RMA, wait for them to approve it, send a replacement and send the dead drive to Sandisk. It used to be the most reliable brand, now it's anything but reliable.
Great size - The small size is useful for staying put, less risk of knocking loose. Satisfactory storage performance.
tiny and fast - great little USB flash drive for my Raspberry Pi operating systems... no problems, just
