External HD Changing the quality of the sound?


Hi everyone! It's my first thread i start in this community and i'm willing to go far in the journey of Hi-Fi audio :)
So i was wondering, is it real that if you put your audio file in an external hd it lower the quality on the outline?
I still don't have dac to test it so i wanted to be sure before putting my library in it, since my external hd is a 2tb and the one i have in my imac is a 500gb and is full...
Also, is it true that the type of connection used for my hd is changing the quality (usb 2.0, usb 3.0, firewire800)?
I know how it could affect it, i just want to know if it is all true?

If you intend to play hirez files, a higher connection speed is important for hardware protocols. In that case use the fastest hardware connection available (esata, firewire, etc). If you are using a network connection, speed is again important, hardwire Ethernet is faster than wireless.
