I took it for use as a flash drive, primarily with a phone and a tablet. When connected to the device, a message appears: "loading .", but the media itself is not readable. Perhaps this problem can be somehow solved, but I have not yet found how. In addition, when connected to a computer and rewriting large files from the hard drive, the copy speed is only 30 megabytes per second. At the same time, in the test program, it is much higher, although lower than stated in the characteristics. As a result, the overall impression of the device is ambiguous. I can't recommend buying.
