There is no information on the packaging except for the volume and support for the USB 3.1 standard, which is misleading because you expect the corresponding speed from a flash drive, but in fact you get a 2.0 standard flash drive with a blue connector. However, the read speed complies with the standard (about 100 MB / s). Writing a lot of information to it is a living hell, but if you use it as a compact archive or a bootable USB flash drive, then it will do.
