Don't have a USB-C port on your laptop? Then the very similar iXpand Go ($60) is the way to go. Handily, you can configure the app to automatically back up photos when you insert the drive. Backing up photos from my wife’s iPhone took a couple of hours the first time. It works well, but it’s not the fastest drive (90 MB/s read, 35 MB/s write). If you want to use this drive with an iPhone or iPad, you must install the iXpand app (not required for Android devices). Storage options top out at 256 gigabytes. This design means that one plug is always exposed, and while SanDisk includes a separate plastic cover that slots on, I fear I'll inevitably lose it. It has a metal casing with a loop for a keychain, and it is very slim. It has a Lightning plug for iPhones and iPads at one end and flips to reveal a USB-C plug at the other, so you can transfer files to or from Android devices and laptops. If you want a flash drive to back up and copy photos and other files from your smartphone, I like the iXpand Luxe.
