Review: Keeps the workflow moving - The SanDisk 32GB Ultra Dual Drive USB Type-C works exactly as it should — fast, stable, and reliable. In my case, this specific drive is required to complete software updates on Nissan products per the manufacturer’s guidelines. These have been on back order for months through Nissan, so I sourced this model directly, had it in hand within two days, installed the software, and was able to get customers back on the road without further delay. Performance has been consistent, and compatibility has been spot on for the intended use. No corruption issues, no failed updates — just plug in and go. At this point, I’ve purchased around 16 of these because they simply work. If you need a dependable dual USB-C / USB-A drive for professional use, this one gets it done.
Review: Washed and Dried!! - I initially bought two of these USB-C/USB-A dual thumb drives to use as backups for my data. I like them because they are compact, reliable, fast, and very convenient. I like that it's easy to carry around in my purse since it's so small. Also, my laptop has a USB-C port and two USB-A ports, so I really like the flexibility that I can use this thumb drive in any of those. Everything was going along fine using these for my regular data backups until....I put one of these thumb drives in my pocket and forgot about it, and sent it through the clothes washer and also put it into the dryer and "dried" it. I heard the clacking around in the dryer and...there it was. And when I took it out of the dryer, it was HOT. At that point, I decided to immediately buy an identical replacement for that one, and not take a chance on continuing to use it. I didn't want to risk that the washed one would fail on me sooner or later, have shorter lifespan, or loose any data. After receiving the third one (the replacement) and doing my regular backup onto it, I then decided to try to the one that I inadvertently washed and dried and....it works perfectly with no loss of data. At least so far. So for now, I have THREE of these and am keeping the washed one as an additional backup thumb drive. I really like the convenience of these thumb drives, the dual USB-C/USB-A ends, the large amount of data that they hold, and the reliability. I don't recommend that you send them through the washer and dryer like I did, but if you do so, well, now you know that it will probably continue to work! I recommend this thumb drive and am very happy with it! I write honest reviews to help others make informed purchases because I read reviews myself and appreciate how helpful they can be. I hope that my review helped you!

## Questions & Answers

**Q: wait, does this have both a type c and a type a connector?**
A: Yes if you slide it one way, the Type C connector is revealed. Then when pushed the other way the Type A connector is revealed.

**Q: Is there a way to attach this to your key chain?**
A: There is a tiny cutout on the rear which presumably is intended for a (thin) keychain or thread loop. But it's so small as to be useless in most cases; I have a lanyard clip attachment with super thin bungee cord to thread onto things like this, and it doesn't fit. I tried to attach the very small split ring from my Swiss Army knife on it, and it was pretty much impossible. You will be hard-pressed to find something which can attach to this. It makes me regret picking this model, as I personally need something that can be clipped on and off from a lanyard.

**Q: Will this lock (with a click) in the center, closed position?**
A: Yes, but it doesn't lock outside of the center very well, I have to hold it from moving to put it into the usb port.

**Q: Will this flash drive fit side by side next to the power cable on a late 2016 MBP? Apple have given very little room it seems to me.**
A: Yes, it should fit right next to the power cables as long as the switch is facing you instead of facing the power cable.

### ⭐⭐⭐⭐⭐ Great little thumb drive, Does actually work with IPhone 15
*by N***H on January 5, 2024*

I’ve had this thumb drive for close to a year now and find it very reliable and convenient for transferring files from my different devices to my laptop. I recently got an iPhone 15 PM and was curious if it would work on it since the new iPhones now have USB C ports rather than lightning ports. I got on here and checked the reviews to see if anyone else had tried it or asked the question of whether it’s compatible or not. To my disappointment all the questions that were answered about it it indicated it didn’t work and that iOS didn’t recognize it and the SanDisk app doesn’t recognize it. Wanting to double check and verify myself I went to the App Store and re-downloaded a couple of Sandisks apps that I had previously used and gave it a shot. To my dismay the reviews were right and the App Store software from the manufacturer does not recognize it. I still wasn’t satisfied with that outcome so I plugged it in again and opened the “Files” app which is the iOS native software that comes on it from the factory. I hit the back button a couple times and got to the “On My Phone” folder and was delighted to see that the IPhone recognizes the thumb drive natively with no extra software required to use it and you get an extra 256 GB of storage(depending on your model). It works like any drive would on your PC. You can create folders, save any type of document you want and even have the option to format the drive if you so choose. Just wanted to pass this along to anyone who was wondering and may not be totally familiar with the iPhone. The only negative thing that I have to say about this drive, is that it does get rather warm when plugged in and using it via the USB port. It’s not really anything that causes any problems, but I can’t imagine it’s good for the lifespan of the drive running that hot.
