NOTE:
Although EZ Writer supports USB 2.0, the actual transfer speed is
dependant on the speed of the USB port it is connected to. If the
USB port supports USB 2.0, EZ Writer works at USB 2.0 speeds (up to
480Mbits/sec); if the USB port only supports USB 1.1, EZ Writer can only
work at USB 1.1 speeds (up to 12Mbits/sec).
When connecting the external drive to a USB 1.1 port, the Data Transfer
Rate is too slow to guarantee smooth playback of the DVD video title.
Apricorn only recommends connecting to a USB 2.0 port to ensure
smooth playback of DVD video titles.
