I bought this to replace a 2-year-old version of the SanDisk 128GB iPhone Lightning to USB Type-A thumb drive that started to fail at backing up files on my iPhone because the device wouldn't be recognized by the SanDisk App. This new version is about as fast as the 2-year-old version, which is why I'm giving it 4 stars instead of 5. The slow write speed doesn't matter because the Lightning port is only USB 2.0 (480 mbps, or 60 MBs), but the read speed via USB-C should be faster especially when the old USB-A version was just as fast as this one. In addition, I have another SanDisk 256GB USB-A / USB-C thumb drive that I bought at the same time at Best Buy for less than 1/2 the price and it reads/writes twice as fast as this. Buyers, beware this thumbdrive is purpose built for backing up your iPhone or iPad with lightning connector. Plug it into these devices and it will automatically launch SanDisk's iXpand Drive app to initiate a backup of your device. If you plug this into an iPad that uses USB-C, then the iPad will recognize it as an ordinary thumb drive and will not open SanDisk's app for backup. You can still copy/paste files to and from the thumb drive, just not automatically backup anything.

I like it a lot because it saves me from paying monthly for more cloud space. It has a nice solid build like a little tank. a protective cap. To be a little picky,I would like it better if it came with a strap and the protective cap was hinged on the device to prevent loss that doesn’t take away it’s wuality.

These are great for size compatibility, but saving memory takes longer then the usual time it takes for external drives 2 save . They are definitely sturdy in comparison

This SanDisk is amazing. It’s simple to use and it works perfectly. I downloaded my photos and videos from my iPhone and transferred them to my Surface.

Perfect and easy way to offload all pictures videos and documents. Fastest way to free up space.
