    • Great way to triple backup your Data
Color: Black Size: 128 GB Style: Up to 150 MB/s
Super fast transfer of your data if you use it on your phone to transfer pictures,videos and files one thing they forgot to mention is that you need the official SANDISK app to manage the transfer painlessly from your phone to your usb-c stick. The value for your money : 5 out of 5, no need for formatting is you are using it with your phone and the app. The appearance is slick and user friendly since it has a regular USB-A . So the quality is there so you won’t go wrong picking this usb-C stick. Connectivity 5 out of 5(both USB ports) ... show more

    • High quality handy storage and transfer device for phone to computer
Color: Black Size: 256 GB Style: Up to 150 MB/s
Super handy device. Much easier and faster than trying to transfer photos from my phone to my computer via a data USB cord which is quite slow and cumbersome. This is also tiny and easy to keep with you. At 256 GB this will hold a lot of photos and videos and makes it easy to share, copy, save to computer, or just store your photos so they aren't filling up your phone storage. I've always had good luck with SanDisk products and most all of my flash drives, cards, and readers are SanDisk. This is very sturdy, well made, and the spinning cover is perfect for protecting the end and easy to switch between the C and the A USBs. Well worth the price. ... show more

    • Smallest, most lightweight 256gb drive I've ever used
Color: Black Size: 256 GB Style: Up to 150 MB/s
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. ... show more

    • Slow, but a good solution if you value carrying lots of data in a teensy, use-with-anything package.
Color: Black Size: 512 GB Style: Up to 150 MB/s
I bought this as "cold storage" for my MacBook Pro M1. My plan was to offshore files from my internal SSD whenever I was running low on space but wanted to keep handy access to movie files and other stuff that didn't rate prime real estate on my SSD. I kind of stopped using thumb drives like this one a while ago. So I was surprised by how slow it is compared to one of my external SSDs or a high-speed memory card. And that's 100% on me. I'm disappointed that big file transfers take so long, but that comes with putting this much storage in a package that's barely larger than a USB-A connector. And teensy size is important for the job I want it to perform. A Samsung 512 gig SSD wouldn't have cost much more than this, and it would have been immensely quicker. But unlike the SSD, the SanDisk thumb drive is so small that I can keep it in my wallet. It's always at hand when I want to watch a movie I downloaded weeks ago, or free up space on a device. I'm also a big fan of the dual USB-A/USB-C combo connectors. It moves easily from my MacBook to my desktop to my phone to my iPad. ... show more

    • Tiny.
Color: Black Size: 128 GB Style: Up to 150 MB/s
These things are nearly microscopic, with one end being the full size USB, just the plug with no base or shroud, and the other being micro-C. No issues on arrival, survived a program that deeply inspects drives for errors or fraud.

    • Double Duty Drive!
Color: Black Size: 512 GB Style: Up to 150 MB/s
Sandisk, as I presume you already know, is among the very finest of memory vendors you’ll find anywhere. These dual drives are exceptionally handy when you need to transfer a file or two but just haven’t got that adapter you meant to throw into your pocket. You really can’t go wrong with SanDisk!
