Slow USB 3.0

I bought a 2TB WD My Passport few days ago for my Macbook. Before doing anything, I installed the Turbo drive in that external drive. 

The problem here is even i plug in 3.0 port, the transfer rate is quite slow compare to what i read on Internet. The maximum I could reach when copying a folder of series (about 20GB) from my Macbook to external drive was 35MB/s…

Someone plz help me to solve this problem.

Thank you very much.

35MB/s is a USB 2.0 transfer rate, check if you really are using a USB 3.0 port, if possible try connecing the passport to another USB 3.0 port on another Mac.
