The major advantage of this flash drive versus most others (including the previous generation of Sandisk iXpand) is that this drive is formatted in ExFAT, not FAT32. This means that you can save files larger than 4GB on this drive – if you have high-quality movie files (>4GB in size), this is essential. The specs also say that you can play video files in many formats – MP4 and MKV being the most popular formats for high-quality video.
There is a workaround for this – you can download and buy a video player called “It’s Playing Pro” from the App Store (costs $4.99) and you can open the file in that app if it doesn’t play properly in the Sandisk app. However, this is super kludgey and annoying. Besides having to pay additional for another app, it takes many minutes for the app to allow you to export and copy the non-supported video file over to the “It’s Playing Pro” app. Furthermore – the “It’s Playing Pro” app can’t play the video file directly off the iXpand drive! You have to COPY THE FILE TO YOUR IPAD/IPHONE – and therefore you need enough free space on your iPhone or iPad to copy the file to. Which, of course, defeats the purpose of having this flash drive – to save the files you don’t have space for on your device, and to use this drive to play them from!
If you have an iPhone this is definitely worth it. You do need to download the app and then have WiFi connection to get it going but the rest is a breeze. It does it all by itself.This device works very well at offloading pictures from your devices without a big hassle. The device works with a SanDisk app which allows you to move photos and videos onto the flash drive, then simply plug that flash drive into your computer USB port for easy transfer, viewing or editing.
