This Flash Drive from Omars is excellent for use with my iPhone. This USB drive is 3.0 so it is immensely faster than the previous 2.0 platform. This is a great option to have on your USB Flash drives that have large capacities like this 64/128 GB product. It also directly plugs into your lightning port and USB port; 80 MB/s reading and 40 MB/s writing speed in USB end. Great product for any looking for an OTG Flash Drive for your iPhone.
