There are dozens of iPhone flash drive options to choose from online, and we've highlighted our favorites that give you the most bang for your buck. Here are the best flash drives for backing up your iPhone!

Omars iPhone flash drive

The Omars iPhone flash drive comes in 32GB and 64GB but has one downside. The plastic protectors on each end aren't attached to the flash drive itself, so if you lose the little plastic nubs, you're screwed.
