Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds

I've got a bunch of these in different capacities and colours for various purposes. They are super useful and I think everyone should have at least a 64gb and 128gb for general purposes. For example, I needed one to run a version of windows while troubleshooting. I was also able to use another to quickly transfer dmp files between my laptop and pc. I also use one for proof of id docs. Backup save files, photos, I wouldn't use one for gaming but as I said you can definitely get an OS runming off one off these. They're also so small that they will fit into any usb port. They basically don't weigh anything. The only downside is that they're so small and weightless that you might misplace them. There are many reasons to keep these around the house and in your day bag. Like any drive they can be formatted very easily, partitioned, named, etc.

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 initially ordered the 512GB version, but it would take too long to be dispatched so I changed to this one. I picked it up from my local post office less than 24 hours of ordering, which is impressive. To my pleasure, this item is much smaller and lighter than what I thought. It is the size of the top two digits of my pinky. I ordered Ultra Dual Drive Go, the cover of which is made of plastic, and it does feel a bit cheap if you look closely at it, but from a metre's distance it looks quite decent. Would prefer a metal cover, though that is a premium which will increase the price I guess. I don't use it daily, so I am not worried about accidentally breaking it. I tried it out on my Macbook Pro, and it transferred data quickly, about 5? GB per minutes if the transfer was from the laptop to it. Slightly slower if I transfer data from another USB to it using a hub. I don't have much experience in data transfer, but this speed has been enough for my purpose. It can get hot quickly, but once unmounted it also cools quickly. I don't want to keep it on for too long to avoid unintentional damage due to heat. Time will tell its reliability. Overall a satisfactory product and will definitely buy SanDisk product again (having had quite a few of them).

This SanDisk Ultra Dual Drive Go 1TB is absolutely brilliant! Blazing 400 MB/s speeds empty my phone’s 4K videos in seconds. The reversible Type-C/A connectors work flawlessly with my Android, Galaxy Tab and MacBook—no adapters needed. Tiny, sturdy black design slips in my pocket. Finally, 1TB of reliable storage on the go! Worth every penny.

Great foe clearing up storage off your ohone i use it for concert videos i recently went to jayz and the videos took up quite a lot of room so this is great super easy to use

Great little flash drive. I use it to store data / footage from my cars dashcam. It is really small, so isn't obtrusive in the cars USB-C port. Worked seamlessly from the first time of use. Good price. Definitely recommend.

Love this USB stick. I bought this for my holiday. Because, it had type-C, i can connect connect to my mobile, laptop and even my camera. Its easy to tranfer, got good transfer rate. Love the fit. Havent noticed any data loss so far. Only thing is , it is very tiny teeny, small one. if you dont have a key ring or a color tag. You definitey lose it somewhere. I have tied it to a keyring and carried on my neck chain as a pendant like in old James bond 007 movie..😂. So, i dont misplace or lose it with out my knowledge. Overall., it is best one that sandisk made with sturdy quality and love the colour.

Decent speed compare to what's advertised. Not great quality build but good for the price range.

Pequeña y súper rápida. Cuenta con puerto tipo C y tipo A.

Fastest USB Flash Drive I've used. I did some data backup for a friend and we decided to copy the data to three different USB Flash Drives. Without boring you with actual speeds the worst drive (SanDisk 512GB Ultra USB 3.0 Flash Drive Memory Stick) took over 5 hours to copy 250GB of photos. This drive did exactly the same job in 1 1/2 hours). I was using the USB A connection and would be interested to know if it was any faster using the USB C?

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!

Easy to use and it works great.
