  • Great little usb stick
Color: Black Size: 128GB Style: Up to 150 MB/s
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. ... show more

  • Great drive for anyone doing meetings.
Color: Black Size: 256GB Style: Up to 400 MB/s
Great for client file transfers. Works with iPhones and MacBooks as well as PCs. Plenty of storage and could easily throw it on my keychain and not worry. Due to me sitting on it for days at a time while operating, it did break after 8 months but for the price can’t complain about what I put it through. ... show more

  • Good value

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

Excellent flash drive with great storage. Very good and small; I would recommend attaching a strap to avoid losing it.

  • Good price for a great product
Color: Black Size: 512GB Style: Up to 150 MB/s
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. ... show more

  • Slow as a snail
Color: Black Size: 512GB Style: Up to 150 MB/s
I bought the 512GB 150MB/s version, the slowest version with the largest capacity. It initially looked good because it has a nice form factor of USB C and USB 3.0 connectivity. It quickly became apparent that this is a terrible product. It simply is unusable due to its insanely slow transfer speeds, and it's by far the worst USB storage device I have used. It feels like you're back in 2002 using the first generation of USB thumb sticks, because the drive would freeze up when you try to open a file or transfer something in. I tested this drive extensively to try to figure out what was wrong. I tried reformatting to ExFAT formats to resolve any compatibility issues with Mac vs PC. I tried using a NTFS reader app on the Mac to read/write NTFS directly. In both scenarios, the drive is painfully slow, and it was slightly faster and more stable in the NTFS format with a NTFS reader (Tuxera). In the ExFat format, it was just unusable and freezes up whenever a file is transferred. I tried using it on PC, and the speed tests (results of tests in images attached) shows ~14MB/s transfer speeds. That is comically slow. I tried both USB 3.0 and USB C ports on the PC, with similar results. I tested on USB C on the macbook air M1, and it was ~20MB/s, slightly faster. My conclusion from my testing is that it's simply not equipped to handle transfers of any large file. This is not a compatability or formatting issue. This drive is slow whether you connect to a Mac or PC. It's slow if you use the USB C port or the USB 3.0 port. It's slightly better if you use NTFS format and use it on windows. This drive is maybe enough if you're someone who only has tiny files, but why would you put yourself through this painful process to use the drive. Just avoid this and buy something with a faster transfer speed. ... show more

  • The Ultimate USB Drive for Modern Devices
Color: Black Size: 512GB Style: Up to 400 MB/s
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. ... show more
