Hello, i am a new user.
I have 2 portable hard drive, USB 2.0 and USB 3.0.
1.) Transfer a file from USB 2.0 to USB 3.0 hdd stuck at 24MB/s and vice versa is that a normal ? or any other way to speed it up ?
no, sorry i just had that question the other day and after 30 years in IT I really should have know before i asked. the fastest you'll achieve is the speed of your slowest connection. In this case it's the 2.0 connection. only when we start seeing devices coming out (like our laptops/tablets) with 3.0 interface we won't actually (theoretically) see the touted 4.8/5.0 Gbps speeds.
