I received this USB 3.0 portable DVD from Roofull and decided to immediately compare it to a very old LG model GP40 USB 2.0 portable DVD. Here's a very simple test and I'm glad I have my LG to compare: - I transfer ONE 3.5GB file from a Win10 install disk, very simple - Transfer speed of the Roofull DVD stays at around 3MB /s based on 5 minute observation (see my photo) - Legacy LG DVD transfer rate stays at 4 MB/s and eventually increases to 7-8 MB/s based on 5 minute observation (see my Photo). I am speechless, my LG USB 2.0 is FASTER than Roofull USB 3.0. I will send it back immediately. However, I like the white version of Roofull which gives it a unique look.
