SanDisk's iXpand is a dual-pronged memory drive with a Lighting connector on one end and a USB interface on the other. It's designed to solve two problems: the first is the alleged difficulty in getting photos off your iPhone or iPad; the second is iOS devices' lack of expandable storage.

Easy to use; Plays back almost any media file; Clean and simple app

Bulky; No USB 3.0; Apple's ecosystem limits what the iXpand can actually back-up

The SanDisk iXpand Flash Drive is ten times expensive than other regular OTGs available in the market and the transfer speed is also not much higher, yet it offers more storage space.

Easy to operate; nice app

Limited file transfer; awkward to handle an iPhone or iPad when plugged in

At $120, the 128GB iXpand works out to an affordable $0.94 per gigabyte. Three additional models are available, but the value isn't quite as great. The $89.99 64GB model costs $1.41 per GB, the $59.99 32GB model comes to $1.87, and the $49.99 16GB drive is the most expensive, at $3.12 per GB.

Fast read speeds; Built-in file manager; Integrated media playback and auto-backup

Flimsy connector cable; App crashed repeatedly when transferring large files in testing

This product looks really nice but unfortunately it keeps crashing. It's ok when u do a few photos at a time but when doing big files it crashes and goes back to home screen

This is a very reliable and useful little device. Pairs seamlessly with my iPhone 6s Plus internal drive. No issues at all. Well, maybe with price which is too steep imo. There are plenty of much cheaper ones out there and probably every bit as reliable I would think.

This a great extra for your iPhone or iPad. I used it to backup photos on both. Since I bought mine, I have ordered two to give as gifts.

SanDisk has released a new version of its iXpand Flash Drive for Apple tablets and phones. This has a slimmer design, new software, and faster transfer speeds.

Apple 's iPhone users have traditionally struggled with the storage space they get in their devices. There are two reasons for this: one, extra storage on a iOS device comes at a premium; two, iOS does not offer options like expandable storage, which is popular in Android devices.

For a ton of iPhone users out there I can see the iXpand Flash Drive coming in handy when they are running out of space from the tons of pictures they like to take. They can copy them over and save to a PC/MAC for storage and then clear out their iPhones.

If you own a iPhone and running out of space here is the SanDisk iXpand flash drive that will help expand your iPhone / iPad storage. This especially made pendrive works with Apple devices and available from 16GB to 128GB capacities.
