The SanDisk Ultra Dual Drive Go 256GB Flash Drive is a versatile and compact storage solution with both USB Type-A and USB Type-C connectors, making it easy to transfer files between old and new devices. Its retractable design protects the connectors, though the plastic build feels a bit delicate. The drive offers solid transfer speeds, particularly with USB-C, and works seamlessly across various devices without needing additional software. With 256GB of storage, it provides ample space for all your files, making it a convenient and reliable tool for on-the-go use.

Surprised how small the thing was when I received it. So easy to carry around, but I’ve also almost lost it because of the size. I got it because of large PowerPoint and Word files I have to save for school, and it does not struggle to save them.

I wanted to get something budget friendly just to save minor projects that I didn’t wanting just sitting on my computer. I love the sandisk ssd drives but didn’t want to spend that much especially for the simple things i need it for, this is nice and small, gets the job done and i love how it has dual usb so i can switch between my computer and ipad with no issues.

I've been the family photographer for over 40 years at family gatherings. I desided to pull together a flash drive collection as a present. This SanDisk - Ultra 256GB is small so they (snowbirds) can take it with them. It worked super fast. Usually when I click eject, other flash drives notify me, still working. But not with this bad boy. Since I wasn't sure if they need a type A or C, this covers the unknown. I was surprised at how much memory was left after I finished loading folders by year. This allows the family to add additional pics of their own. I can't speak to it's longevity since this is a recent purchase.

Love the size! the multi-port makes it convenient for either connection to the laptop or ipad. It's fast loading and transferring files. Highly recommend! I do wish it had an endcap to protect the opening but since I keep it in a plastic box I don't have to worry yet about dirt getting into either opening

We were trying to transfer data from a laptop to a new computer, so we needed these flash drives for the project. I love that they are USB/A and C as the other USB runs my mouse. These flash drives worked great and are now empty again and awaiting the transfer of hundreds of photos for storage. Easy to use, and a good prices for the high storage amount. Highly recommend

I like software that controls this USB. It's also fast, and of course, portable and has more than enough space for my travel editing needs.

From the moment I plugged it in, the dual-connector design (reversible USB-C on one end, standard USB-A on the other) made life so much easier. No more adapters or hunting for the right cable! I use it daily to offload photos and videos from my Android phone (USB-C) straight to my laptop (USB-A), or back up files between my tablet, Mac, and Windows PC without any hassle. The swivel mechanism protects the connectors when not in use, and the built-in keyring hole keeps it secure on my keys or bag—super portable and hard to lose despite its tiny size. Performance is impressive for the price: read speeds hit close to the advertised 400MB/s on larger transfers (real-world tests show around 300-400MB/s depending on the host device), and writes are solid for everyday use like moving large videos or documents. It's plug-and-play—no drivers needed—and works flawlessly with phones, tablets, laptops, and even OTG-supported devices. The 256GB capacity is massive; I've stored thousands of high-res photos, 4K clips, music libraries, and important docs without batting an eye. SanDisk's reliability shines through—I've had zero issues with data corruption or failures after months of heavy use. It's durable enough for on-the-go life, though it does get warm during big transfers (nothing alarming, just normal for high-speed flash drives). If you're someone who needs versatile, fast, and reliable storage in one compact package, this is it.

I like that I can use this with both standard usb and usb c devices. Very compact good capacity and inexpensive.

large storage in small size. easy to carry around and fast. having both USB-c and 3 is great.

This little guy has proven far more usefual than I even originally intended. Main purpose was to transfer files easily between my laptop and Steam Deck with the handy USB A-or-C functionality, but I've ended up using it for far more than just a shuttle for game roms - it's super fast and the seamless adaptability (and tiny size) makes it perfect for long-term storage of any number of critical files and photos you may want to keep - and obviously you don't have to worry about data decay with a flash drive - for $18, couldn't be happier! Buy two!

This is the best thing since sliced bread. It’s extremely convenient for your phone, computer, tablet, whatever has a usb-c port. I’m glad I got this on sale, it’s also easy to use. As small as a pinky, perfect for an influencer or an editor lol. 10/10 I would buy so many if I needed that much storage.

This tiny device has been great. Love the dual functionality of USB C and A. The 256GB of storage provides for plenty of data capacity, the dual capability provides great flexibility and the tiny dimensions make this all super portable.

Love this. Bought it on sale though, so might love it less if I paid full price. Works fantastically, very fast and reliable. And...SO MUCH SPACE! Great for quickly storing or moving large files off my phone/computer. Only potential issue is it's TINY and dinky. Smallness makes it feels flimsy. Like it could break easily. Also again...so tiny. I attached a red string to it and a red sticker to keep track of it, and I never leave the house with it. Highly losable. Also makes the base of my (new, Samsung Galaxy Note) phone very hot, after about 20 mins of use.

Small and super convenient for Laptops with these new usb type c connections. Large storage amount. Easy to toss in your work bag and store large amounts of documents and music files.

Excellent speed and great amount of storage. Nice and compact for traveling.

Talk about compact and storage! I was able to get three old USB’s transferred onto one of the new!

Bought to backup photos and videos from my phone. Fast and easy to use. Does exactly what its supposed to. Learned my lesson with cheaper brands. Love how it connects right to my Samsung Galaxy phone without any extra adapters to have to keep up with. Small enough that its not too easy to lose, but not too big to hang on a keychain either

It's small... I holds a lot of stuff.. I like that it fits in my pocket. Doesn't get hot.

Easy to use, size is just right, small but just what I needed, lots of memory
