I've tried competing memory expanders for iOS but I think the iOS Card Reader ($39.99) from PhotoFast may finally earn a prized place in my gadget bag. Of course, Apple doesn't like to let users expand their memory, making you choose 16 GB, 64 GB 128 GB of storage. With Lightning-based memory expanders, you no longer have that limitation. They do require custom apps (free of course) to access movies, photos, songs, and more, but that's an understandable tradeoff.
