WD Passport USB 3.0 gets slow transfer rate, how to speed it up

"I have a WS Passport USB 3.0 external hard drive with about 400GB of data saved in it. And recently, the WD external hard drive suddenly becomes extremely slow with a low transfer rate. 
For example, when I tried to copy a single Word document to the drive, it would take me about 5 minutes to complete. 
The WD drive has about 1TB storage space in total, which means that I still have more than 500GB free space left. But now, the drive becomes very slow for file transferring and saving.
