It's certainly not 3.0. Recording speed is maximum 9 Mb/s, on average 5-7 Mb/s. Readings no more than 30mb. / s. On the USB 3.0 port, reading and writing can at least sometimes get the maximum, though for a fraction of a second. At 2.0, the speed drops by two. Has been serving for six months. Sometimes it loads a port or computer if a lot is recorded or the file is heavy. But while everything is read and written. As a custodian of information - excellent.
