From the time USB OTG was announced for the mobile market, it never really caught on, as pretty much anything designed to work with a phone/tablet did so by Bluetooth. Now the Japanese company JForce aims to change this by being one of the first with a USB OTG flash drive that features a micro-USB plug on one end and a regular USB plug on the reverse end.
The JF-UFDP4S is a little small at just 4GB, but apparently with USB OTG's limited performance, it is reported to take 20 seconds to transfer 50MB. For comparison, many modern USB2 flash drives can transfer 50MB in as little as 2 seconds or even under a second for some USB3 models.
Before rushing out to get one, you will also need to check device compatibility. Apparently, just 10 Android phones and 5 tablets officially support this USB flash drive.
