This SanDisk iXpand Flash Drive is one of the best ways to add additional storage capacity to an iPad or iPhone. Find out how easy it is in this review.

Using a iPad or iPhone you have grown to having fixed storage on these devices. They don't have expandable storage card slots like some android devices and you are pretty much stuck with what you have.

SanDisk's iXpand flash drive brings additional storage to your Apple iOS device, but is the performance it offers enough?

My wife and I recently returned from our honeymoon in the American Southwest. We toured the Grand Canyon, Bryce Canyon, Lake Powell and the Hoover Dam over the course of nine wonderful days.

I bought this for my Mother-in-Law and she is so impressed by the memory stick; It is so easy to use

Nothing I can add

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

T his is a little more than a simple USB 3.0/Lightening data transfer and storage device. Its first trick is packing a small battery into the unit, so extended use via Lightening won't need the iPhone or iPad's battery.

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

SanDisk is one few companies trying to help users get around this problem. The iXpand Flash Drive does two major things: it helps you carry more data around than your iOS device(s) can store, and it helps you copy files to and from PCs and iOS devices without going through iTunes.

Well-designed app; Portable; Convenient for file transfers

Requires charging; Limited to USB 2.0 transfer speed; Awkward to handle an iPhone or iPad when plugged in

They might have become a rage all over the world, but iOS devices - whether it is the iconic iPhone, iPad or iPod touch - have had an Achilles Heel: that of non-expandable storage.
