Saving to disk (writing) was incredibly slow for some video files recorded in 4k. Tests showed 29-30/MB at best, but read speed is stable at 299/MB it is the fact that it has a usb-c connector, just buy an adapter for your regular usb drive and plug it in. even my old seagate external hard drive is faster than this, what a new product such a one disappointment was hopes. If you want the best speed, get an external SSD. Samsung T5, G-Drive, Atom and even WD have an SSD that will give you the best bang for your buck. They're all relatively portable. If you just want a good usb drive i would say sandisk and use adapters it sucks but all these guys have yet to practice kinks with flash tech and a type c connector wen n you know something better - please write!
