Slow file transfer speed?

I have my WD passport connected via USB directly into my new WD MBLD and i am transferring files across; photos, tv shows, films etc. 

I am seeing the average transfer speed is about 1MB/s.  Is this normal? It seems slow to me and it’s taking forever to transfer my media across. 

When using your computer, the data leaves the USB disk, goes across the network to your PC, then goes back across the network to the other share.

That’s unfortunately just the way shares work, and is not unique to the WD.

If your PC is on WiFi, that could easily account for the slowish speeds.

yes my PC is on WiFi. 

Thanks for the explanation.
