Ultra Dual Drive Go 128GB, USB-C & USB-A, Up to 400MB/s Read Speeds

Excellent drive, superfast connectivity and transfers. Connects to both (as described) to USB-C (mobile) as well as USB-A drive (laptops/PCs). Fits easily anywhere (not a bulky drive) and does not need much space (sleek device). Solid build and format capability, and works well with both windows and android instantly without any hassle. Great to transfer personal files such as photos and videos immediately from the mobile to save on space. Have tried on two different mobiles (Samsung and OPPO) and both mobiles connected seamlessly. My only additional observation would be is to make sure OTG is enabled in settings on mobile before plugging in (e.g. OPPO mobile needed this one additional security step before recognising the drive, the mobile turns this feature off after about 10 minutes - great feature to have for security). Great value for money and functionality. I could connect this drive to USB-C on laptop as well (if available - please see image with drive connected to USB-A, USB-C on laptop). A fantastic solution for anyone looking for an easy solution to save disk space on mobile and easy transfers of files from a mobile to a laptop/PC. Would definitely recommend.

I recently picked up the SanDisk Ultra Dual Drive Go USB Type-C 512GB Flash Drive, and it has quickly become one of my favorite tech accessories. Here’s why: Design & Build: The design is sleek and compact, making it easy to carry around on a keyring. The swivel feature protects both the USB Type-C and Type-A connectors, ensuring they stay safe and intact. It’s lightweight, portable, and built to last. Performance: The performance is fantastic – I’ve been getting speeds up to 400 MB/s, which means transferring large files is quick and painless. Whether I’m moving high-res images, videos, or documents, it’s fast and efficient. Compatibility: This drive is super versatile! The dual connectors (USB Type-C and Type-A) allow me to easily transfer files between my Android smartphone, tablet, Mac, and even Windows devices. No need for extra adapters or cables – it just works. SanDisk Memory Zone App: The SanDisk Memory Zone app is a bonus for Android users. It makes file management and backups a breeze, and helps keep everything organized on my phone. Conclusion: If you need a reliable, fast, and portable flash drive that works across multiple devices, the SanDisk Ultra Dual Drive Go 512GB is a great choice. It combines speed, compatibility, and convenience in one package!

Great product. An app must be downloaded but the app itself is very intuitive to use and has a great user interface. My only issue is it’s advertised as a 64GB flash drive but the app only shows an available 61GB. That was just odd to me but still good for the price.

Compact and brilliant device

Got this to plug into my cars dashcam app which records through onboard cameras so far seems to working fine very small in size but decent memory probably versatile too and could be used for many different purposes and on other devices

Was looking for a duel connection usb stick to quickly transfer files to and from my phone and took a chance on this one, it almost has no weight to it and its also tiny, by far the smallest usb I have. It's a simple flip and you have usb-c or usb-a to plug in, as its for transfer only I just went for the 128gb size. Just to be aware as its plastic it would not stand up to much misuse, it may be ok if dropped due to its weight but I suspect it would break easily, I keep it in an obvious place so I don't lose it. If you had it on keyring with metal keys etc it may eventually get chipped and broken, if you want to carry it with you I would put it in your wallet or on its own around your neck as you wouldn't even notice it, been using for a while with no issues at all, highly recommended. I meant to add that I seems to got hot pretty quickly which I haven't noticed on other usbs I have , they are metal so will dicipate the heat better, not an issue for me as I transfer files but worth noting if you will be having it running longer term.

It was such a great deal when I bought it! It is very cute with lovely colour. It is working well with Android phone. No hassle to connect or install to the phone at all. Also, fast operating system!

I bought this USB stick to transfer data from my computer to one of my family members phone and it worked flawlessly. Having both a USB-A port and a USB-C port on the one USB has been more useful than I expected. The front of my computer has a spare USB-A port on it and my laptop a spare USB-C port which means with this one USB stick I can easily transfer data between the two without having to use any data. The read and write speads are sufficient for what I need it for but don't expect to be transferring several GB files in just a couple seconds. The speed does slow down quickly when transferring large files but this is to be expected. One unexpected benefit is the swiveling function which I find very fun to fidget with. It snaps into place when the USB stick is aligned with the case but does swivel very easily. I do wish the snap was a little more tactile and kept the USB aligned with the case a little better but this doesn't change my rating at all.

I bought this to save some space on my phone, when I received it I thought I bought the wrong item because it wouldn’t work with SanDisk Memory Zone on the iPhone 15 Pro. So I thought it may not be compatible with my device. However SanDisk customer support was able to help me navigate using it via the Files App on my phone. It is not compatible with SanDisk Memory Zone on the iPhones, only Androids. I feel that this was the perfect solution for what I needed! It has usb C on one side and usb A on the other so I can use it with my phone and laptop interchangeably. It seems well made and pretty durable. Connectivity is fine once I figured out how to access it 🙃 I love how small it is and that I can put it on a keyring, lanyard or carabiner something to keep it from getting lost.

Very handy having both a usb and type c port. Has a short installation app for phones but great for that easy access when it has two ports to plug and play. Very compact! So small in fact that I have to clip it with a keychain so it doesn't disappear on me, but that's a compliment!

Very precision, compact and usable flash drive ever. No issues, always works to perfection.

Easy to use and it works great.

Smal fast perfect!
