    • Reliable, Fast, and Worth Every Penny – Perfect for On-the-Go Storage

The SanDisk 256GB Ultra Dual Drive Go USB Type-C has been a game changer for transferring files between my laptop and phone. It’s incredibly easy to use, with smooth plug-and-play functionality and fast transfer speeds. The durability is impressive too—I’ve tossed it in bags and pockets without any worry. The quality feels premium, and I haven’t experienced any data loss or corruption even after frequent use. I also appreciate how easy it is to remove from USB-C ports without excessive force or wiggling. For the value for money, this drive delivers top-tier performance and reliability in a compact, dual-interface design. A must-have for anyone juggling devices! ... show more

    • Great value. Worth every penny
Color: Black Size: 512GB Style: Up to 150 MB/s
Ok so I purchased this for my new car in Jan 2021 to use with my permanently integrated dash cam. I have been using this almost everyday except vacations and occasional weekends and as long as I am driving, it is on. To date I have not had a single issue with it and even if it stopped now I have used this for 4 years give or take a few weeks and it has served me well. I would buy it again in a heart beat. ... show more

    • Easy and efficient.
Color: Black Size: 256GB Style: Up to 150 MB/s
Easy to use and double the space on my wife’s phone. We used this to backup all of my wife’s photos and videos. Price was excellent compared to other brands with similar storage capacity. Really like the ability to use usb c and a by simply flipping it over.

    • UPDATE -No Scam. Biggest scam of the 2025- I was wrong
Color: Black Size: 128GB Style: Up to 400 MB/s
This is a scam! I bought this thing as 128 GB and it turns out has only 750 MB This has been the biggest scam of the year so far and apparently I didn't check it immediately and now I cannot even send this useless thing back. I am disappointed with Amazon. Update. I have to appolagise but I made a mistake. Have no idea how it happened but now I realize that The item was working fine but I must have done something wrong on the format and Now I can see clearly the item is working fine and i was unfair in my first review. Please forgive me. I am not sending the item back and will keep it and hope you can forgive my misleading first review ... show more

    • Convenient and compact
Color: Lavender Size: 128GB Style: Up to 400 MB/s
PROS: It's tiny, cute, and I got it on sale. It works as advertised. I moved files from my Win7 PC to my Android Moto Play without any special app or program needed. From Moto to PC works just as easily. My PC has a USB-A port and my Moto has a USB-C port. CONS: The case is thin plastic and is alarmingly flexible. It seats firmly in the USB port of my PC, but must be removed very gently. It gets hot (as others noted) and it is hard to grip, especially if other ports around it are in use. (A similar, metal-cased might item might dissipate heat better, but not so fast..... Reviewers say that gripping that drive too firmly by the USB-A end caused a slight bend that now prevents it from going into the USB port on their PC. BOTTOM LINE: Good for light use and a quick way to move files between phones or between PC and phone. Buy a spare ... show more
