An ordinary flash drive is fine with it, but the write speed is rather low. There is no marking on the package with data transfer rate, so I think that this is not a defect, but a feature of the model. Everything would be fine, but I have cheaper usb 2.0 flash drives that have a record of up to 18. And some have only 4.8, but it's still higher. So I would probably buy another model and probably buy it.
