After I received this adapter, I transferred over 700 videos to it, with lots of room to spare. It gets a little hot when it's running but otherwise, no problems. Decent product.

I bought this so that I could have a second OS that I could use on any of my computers. I needed a large storage device in a small package. I was a little surprised at how small it was but smaller is better for my case. I've been running an OS from it for about a week now and had no problems. It boots as fast as the Windows 11 that is on my hard drive and I can have my OS and all the files the same on any computer. Having the 2 ports to use also comes in handy since some of my computers have USB-C that is not being used for something else. I also felt the price was good for 512GB. I would recommend it.

SanDisk’s 512GB Ultra Dual Drive Go USB Type-C Flash Drive (SDDDC3-512G-GAM46) is an impressively versatile, high-capacity flash drive that has greatly enhanced day-to-day data management and device connectivity. This in-depth review covers real-world usability, speed, durability, and features, making it an essential guide for anyone considering this dual connector drive. The most notable advantage is the dual connectors—USB-A and USB-C—which allow for seamless file transfers between legacy and cutting-edge devices. This flexibility makes it ideal for working with smartphones, tablets, laptops, and desktops. No need for adapters, and switching between devices is as simple as flipping the drive’s cover. It’s especially useful for consolidating files or backing up media on the go, making transitions between work and personal devices absolutely hassle-free. With its 512GB capacity, the Ultra Dual Drive Go wipes out storage anxiety. It easily stores entire photo libraries, massive video files (including 4K and 8K footage), and countless documents or software installers. While the advertised read speed hits up to 400MB/s (USB 3.1), and typical transfer rates are fast and reliable for everyday use, some users note that sustained large writes (like transferring several 100GB videos) may cause the device to heat up and throttle speeds. Nevertheless, moves like a 160GB file in under 3 minutes show it’s more than competitive among similarly-priced drives. It’s not engineered for specialized pro-level tasks (such as direct ProRes video recording on premium smartphones), but for most consumer needs, performance is more than satisfactory. The sturdy swivel design both protects the connectors and makes the drive highly portable—perfect for pockets, bags, and busy schedules. The keyring hole offers extra convenience, and the compact form factor is praised for ease of use and daily carry. Notably, this isn’t a fragile accessory; the robust build feels solid and holds up well to constant handling. Setting up and using the Ultra Dual Drive Go is a breeze. Plug-and-play compatibility ensures immediate file access, while advanced users can enjoy features like automatic photo backups through SanDisk’s Memory Zone app on supported Android devices. Whether managing files between a USB-C smartphone and USB-A laptop or freeing up storage on-the-fly, it consistently delivers a smooth experience.

Works well in general. Although it is painfully slow when receiving/writing data from my Apple MacBook Pro.

A very nice and very, very small usb stick. It arrived formatted as FAT32 but I reformatted it to exFAT due the file size restrictions inherent in FAT32, I mostly use it to copy images off of my smartphone and those copy very quickly, although it also is handy for copying files from my laptop to my desktop and back. So far I am pleased with the purchase and the small neck at the usb connection allows me to connect it to my smartphone even with its case on. Those usb sticks that I already had that did not have that neck would not connect to my phone unless I remove it from the case.

Needed a large enough USB storage device that would work both as an OTG device for backing up phone data off multiple devices, but also on standard PC's if necessary. This was the perfect choice. On one end is USB-C male connector, which actually has a longer metal plug. This make it easier to fit the USB-C port on the phone without taking off the phone case. The other end is a standard USB-A male connector that is also longer and can be inserted into recessed ports on a PC or laptop. The physical drive itself is tiny. And the casing is plastic (not metal). So it's extremely lightweight, and narrow enough so that it can actually fit inside the cap of fountain-pen. The only complain I have is the SanDisk software on Android. It kept failing to recognize the exFAT format that was default on the drive. After some troubleshooting, I realized that the drive first had to be formatted by Android (via Android OS's Storage setting), and not via Windows OS. Once the blank drive was formatted via native Android's Storage option for exFAT, it worked on Android across multiple phones, and also in Windows. Otherwise this software issue, this device was perfect for my needs.
