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

Once the app was downloaded it did all the work for me, loading all photos then asked if I wanted to edit these, which I did

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.

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 a must-have accessory for those with a newer iPhone or iPad.

The SanDisk iXpand Flash Drive instantly adds up to 128GB of storage space and it can work as a USB thumbdrive; Its iXpand Sync mobile app works very well both for media playback and content backup

The drive can't hold files larger than 4GB and only supports USB 2.0

SanDisk's updated version of the iXpand Flash drive provides you with 128GB of additional storage for Apple devices.

Slim and pocketable design; Directly record and play content from the drive; Easy transfer with automatic backup

Large files cannot be transfered due to file format restriction

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.

Lightweight; sleek design; Viewing video on iPhone; Sharing files via Airdrop; Securing sensitive files

Speed; Price; Could be obsolete with next-generation iPhones

Good product, purchased because I wanted something small. Careful, though, as it makes it easier to lose (this is a replacement for a similar one I lost), but this one has a rubber loop at the end which does make it easier to attach to things (and thus less likely to lose.)

Android users have always enjoyed expanding storage capabilities of their devices using either memory cards or USB drives. Apple, on the other hand, has never added an expansion slot on the iPhone.

+ Easy transfer to iOS devices; + Long Battery Life; + Nice App

- Large in Size

SanDisk's iXpand in its second iteration is a solid, high performance solution for iOS users. On the downside, it carries a price point well over $1 per GB, making it one of the more expensive solutions.
