I love that it offers such a huge amount of storage in such a discreet design. Build quality feels solid, and it has worked flawlessly so far with no disconnects or overheating issues. This is an ideal solution if you need extra space for your laptop, car stereo, or even a media library to carry around in your pocket. ✅ Very compact & low-profile design ✅ Fast transfer speeds with USB 3.1 ✅ Reliable, with generous 256GB capacity ✅ Great for travel, media, or everyday use Highly recommend this flash drive for anyone who wants big storage in a super small package!

Product declared capacity (256GB) is not true. It is less than that. My purchased flash drive shows 249,986,547,712 bytes under properties on Windows.

This Flash Drive is a great way to back up your computer. USB stick drives have come a long way! I am using it with a laptop that has a flash drive and it works perfectly. I really like the small form factor because most people will hardly know it is there because it is so compact it barely sticks out. Using it with a 3.0 USB port (usually blue) makes a noticeable difference when compared to the previous USB versions. Many newer compact laptops are coming with USB C ports only so make sure the device you are going to use this with has a full size USB port or you will have to use an adapter.

I purchased this for use with my Bambu Labs H2D printer. The USB port is on the top of the machine and I didnt want to unintentionally end up bumping a larger drive. This has worked beautifully and great price for the storage.

I'm a dj and was in need of more storage space since laptops come with small drives now. This usb drive was on sale and even though it's smaller (256GB) than the other drives around the same price, I felt the speed and portability made up for it. I have my entire library (music I constantly use) with tons more room. Just like others stated, the usb drive gets warm/hot. I really thought it was plug and leave but you still have to eject and plug back in which is a little scary because the housing is plastic instead of aluminum like the earlier versions. Overall great tool to use for backup and or main storage.

Excellent sleek design. Very fast. And eat to use.

The SanDisk Ultra 256GB USB 3.1 offers an affordable solution for fast and dependable data backup on your USB 3.1 devices. Its compact design allows for secure storage in various locations, shielding it from magnetic fields and protecting against data loss caused by EMP. This compact flash drive is truly impressive, as it has a minimal profile that stays out of the way and goes unnoticed. I find it extremely useful for freeing up memory on my Lenovo YOGA. It's incredibly user-friendly, requiring no formatting—simply plug and play. I do regret not purchasing multiple units during the sale period; it's that good!

When I bought a new HP Chromebook, I decided to splurge and get this also, with the intent of expanding the Chromebook's onboard storage. It turned out much better than I expected. It works exactly like the micro-SD card I transferred from my original to my new Chromebook. But I cannot believe how convenient it is. Yes, it is little and fits into the USB port and is practically unnoticeable. It never get in the way. Despite its diminutive size, it has a huge usable memory. It is large enough to store thousands of photos, music tracks, and movies with room to spare. What is best, however, is that it is a USB device. It is a snap to transfer it from my Chromebook to my desktop -- and out to the USB port on my car stereo. It is fantastic to be able to listen to my own music when I am bored with broadcast and satellite radio.

Tiny, well built, fast... This could be the perfect thumb drive. Don't recommend lending it to a coworker. Kind of thing you won't ever get back! It's also cheap so no big deal.

Needed extra storage space for work and this drive was perfect.

I was looking for a flash drive with a sizable capacity for my music files to play with my Yamaha A/V receiver( right now I have 75gb of flac files plus a few gig of High Res music).I saw this at 50% off so I went to pickup one immediately.. Now I have extra space for more, I am always adding albums every now and then and it plays flawlessly with my receiver...and it is fast enough for music transfer..highly recommended for really, really portable backup...and it was a no brainer for the price by which I paid for....and the added bonus is that, it is so small that it is hardly noticeable when it is plugged in my laptop. Now I can switch devices easily if I want to play my music collection

Compact SanDisk Flash Drive is so tiny that you can leave it in your laptop or desktop computer 24/7 and it won't get in the way of slipping laptop into carrying case/sleeve. No risk of Flash Drive getting snagged and breaking as with longer flash drives. Communication between computer and Flash Drive is rapid. Holds an impressive 356GB of data (equal to the entire solid state hard drive capacity on one of my laptops and half the capacity of another). Gotta love technology. How did our grandparents ever live without it.

I used a single 3.0 USB hub to copy from a 3.0 USB hard drive to this product, SanDisk Ultra 256GB 3.1 Flash Drive. The file sizes and directory trees were irregular, non-optimum. A different 64GB 3.0 Flash Drive averages 7.6MB/sec. The product under review averaged 25MB/sec. 3.0 USB hard drive to 3.0 hard drive with same files averaged 80MB/sec. The form factor is convenient for inserting or disconnecting. No lights. Loop for a cord. Shorter than a thumb nail. I like the speed, capacity, price, and form factor.

Nice and small, seems fast enough. I'm worried I'll break the plastic surround on the connector someday.

This works Great and super small. Fits on key chain and is easy to carry around!

Amazing amount of storage space for such a very small device. I have some small flash drives like this that don't have anywhere near this capacity and some of them get very hot during use. I was afraid that might be the same with this one but, happily, it does not get hot.

I needed a flash drive for my car as it doesn't have a CD, it doesn't work with iPod's and the phone access is limited. But it does support USB drives with a clunky interface, at best. I had other flash drives but they stuck out too far and I have accidentally knocked them out or broken off because of this. I lucked out stumbling on this little gem at BB's! low profile, large capacity and fast. I use one for music and a second for the vehicle security. Will snap up a few more when available.

Fantastically tiny thumb drive. It's so small if you have an extra USB port you'll forget it's there. It's a good cheap solution to low priority storage.

Great portable storage in a very small package. I like these especially for music to use in my car since they don't stick out so far and risk getting bumped. Pretty amazing caoacity for the price. I have had a couple fail after many many rewrites but generally work without any problems. Also the speed is good enough for most purposes.
