Here’s why:Design & Build:The design is sleek and compact, making it easy to carry around on a keyring.

This is a compact USB drive with Type A and Type C connections that, formatted as FAT32, can be written to and read by Windows and Mac OS. The drive also comes with instructions and an app to use it with an Android phone with USB C connection.In terms of read and write speed I would rank this as medium to slow. Initial burst speed is 73Mb/s write and 150 Mb/s read, but this slows to a still respectable, for the price, 35.7 Mb/s write and 80 Mb/s when transferring large amounts of data. For example it takes 3 minutes to transfer 2Gb of data (on the 128Gb version).The compact dimensions means that there is plenty of room to slot in another drive or USB C connector on my Macbook Pro. In use the drive gets warm but not hot.For portability the cover flips over to protect the USB C connector while the USB A plug is recessed. The connection to my Macbook feels very secure and indicates good build quality as you would expect from Sandisk.Good value, then, with one star deducted for slowing write speeds when moving data.

I can't comment on durability as I have a special place for it in my bag and it's always safe there. But first impressions is that it's probably going to break if dropped. Other than that, i like how compact it is. I also am using it for an iphone 16e and it works really well. It does get hot when transferring data but I use it for casual photos and videos so not a problem.

I got the SanDisk Ultra Dual Drive Go 256GB, and it’s been fantastic! It plugs seamlessly into both USB Type-A and Type-C ports on my Mac and Android phone. Delivery was quick, and the transfer speeds are super fast. The 256GB capacity is great for freeing up space on my phone and laptop, especially for photos and videos. It’s well-built and strong—I’ve dropped it a few times, but it still works perfectly, making it great value for money. The included key ring holder is a lifesaver for this tiny USB, though I haven’t tested its water resistance, so I’m careful. It really shines in functionality! I have also tried and tested connection with TVs, greatly working.

Purchased black 256gb stick to store a large amount of photo's. Currently have many USB sticks, but went for this one in particular as it has 2 different connectors so can be used both with a standard USB connected to a laptop, but also to a USB C to download from a mobile phone (its compatible with samsung).It is a lot smaller than i expected so keep it somewhere safe! The USB C connector has a flip-over cover to protect it, but strangely the normal USB connector end doesn't come with any cover. I think for safety when not in use a safety protection cover would have been better on both ends. USB connection in laptop port is a tight fit to get in and out. USB C fits mobile snuggly. Downloaded 200+ photo's from laptop to this sandisk in no time at all. Very impressed with it - dual connection is the way forward. Accessed downloaded photo's many times both using laptop and via mobile phone with no issues. Still loads of room left on stick for further photo's as required. Consider this item good value for money.

I recently purchased the SanDisk 256GB Flash Drive, and I have to say, it's an absolute game-changer! The compact design makes it super easy to carry around, and despite its small size, it offers plenty of storage for all my files. I love how fast it transfers data—whether it's videos, photos, or documents, everything moves quickly without any lag. Plus, it works seamlessly across different devices, making it versatile for both work and personal use. It's a reliable, high-quality product that I can count on. Highly recommend it for anyone looking for a portable storage solution! I hang it from my lanyard so I can always have an easy way to swap, share large files. The usb and usb-c on each end is definitely the way forward. Plugs into anything!!

Bought from the amazon resale for around £15.35. Useful as you don't need an adaptor when switching between USB C and USB A. The item was much smaller than I anticipated so initially I thought amazon sent the wrong item! Very happy with purchase as it has a large capacity.
