Small with big storage
The SanDisk 256GB Ultra Fit USB 3.1 is an excellent choice for anyone looking for a compact and high-capacity USB drive. I have been using this drive for several months now, and I am very impressed with its performance and reliability. One of the things that I really like about this drive is its size. It is incredibly small and compact, which makes it very easy to carry around with me wherever I go. Despite its small size, it has an impressive capacity of 256GB, which is more than enough for my needs. The drive also has a USB 3.1 interface, which provides fast transfer speeds. I have been able to transfer large files such as videos and photos in just a matter of seconds, which is very convenient. In terms of build quality, the SanDisk 256GB Ultra Fit USB 3.1 feels very sturdy and well-made. The drive has a metal casing that gives it a premium look and feel. I have accidentally dropped the drive a few times, but it has held up very well and has not suffered any damage. Another great feature of this drive is its compatibility with a wide range of devices. I have used it with my laptop, desktop, and even my smart TV, and it has worked perfectly with all of them. Overall, I am very happy with my purchase of the SanDisk 256GB Ultra Fit USB 3.1. It is an excellent choice for anyone looking for a high-capacity, reliable, and compact USB drive. I would highly recommend this drive to anyone in the market for a new USB drive.

Best little file safe I have ever used!
I have had this for several years now, it is still functioning flawlessly, very durable! It does everything I need, and so far, I have not come close to filling it upI use this everyday! This was worth every penny. It is small, so does not get bumped while in the computer, is easy to install and remove, and gives me the security I need and all my important files at my fingertips no matter what computer I am using at the time. Would buy again and again.

Still useful, even in 2026
To be completely honest, I would not normally recommend a flash drive without USB C in 2026. That said, this one is such a good value for what it is. It is perfect as a simple install drive for Windows or a Linux distro, and it is just nice to have a few of these around the office when you need them. Small, reliable, and does the job without any fuss.

Nice little flash drives.
So far I have two of these flash drives. Both are currently connected to my laptop via a USB 3.0 hub. One is older than the other. Both have been functioning well. I have the 256 gb version on both. Nice amount of space for not a lot of money, helping me keep my hard drive cleaner. At one point I did have the older one directly connected to the computer. I've not noticed any difference in the transfer rate since I swapped it to the hub, which was something I worried over. Both have nice transfer speeds, more than geared to my needs. *Edit, August 2021* Since I originally wrote this review sometime in 2020, I have invested in several more of these drives. I now have somewhere around 12 to 15 or so ranging in size between 64 gb all the way up to the 512 gb version. They are used in multiple applications. Three are "TV" drives, attached to the three smart TV's in the house (unless I'm adding to them, in which case they spend some time in one of the two USB hubs I have.) One is about to be geared towards my Wii, and the rest are computer storage for my desktop and laptop. Those "computer storage" ones are the ones that live in the hubs full time. I use them for everything. I've a massive music collection, and that is now split between about 4 of the 512 gb's. My movies are on another, one is for "computer file storage" (which is my catch-all drive for program files, pictures, and documents.) I could keep going with the uses I have for these, but the long story short is I no longer have to worry about losing everything if my hard drive fails me. Because even if one or two of these lock up, loss will be minimal. Speed is still not an issue at all, And to date, none have locked up on me, and they see quite a bit of use.

I specifically searched for a USB-C flash drive and this item came up in the results. Based on the product title, photos, and description, I believed it was a USB-C drive. However, when it arrived, I was disappointed to find that it is actually a USB Type-A drive. Nowhere in the listing did it clearly state that it does not have a USB-C connector, and the images were not clear enough to show the difference. This is misleading and frustrating, especially when you rely on Amazon’s search and product listings to be accurate. If you're looking for a USB-C drive, this is not it.

This storage is exactly what I was looking for - small and compact so it won't get knocked out of my computer and damage my files, with plenty of space to store my teaching documents and transfers files at lightning speed. I'm so happy with this purchase. Highly recommended Ǔ

Received these in good condition. Got them during the Prime Day sales with good prices. Plugged into the laptop USB port for additional storage. Work well so far.
