My Passport Slow Transfer Rate

I am currently having a WD My Passport 2TB, at first the performance of this device was pretty good more or less the same as people reviewed on the internet, but recently I have been recognizing the performance degradation on this device transfer rate, both on PC to My Passport and My Passport to PC transfers.

From PC to My Passport transfer, I am only getting about an average of 45 MB/s transfer rate. Transferring from My Passport to PC is even worse with only an average of 30 MB/s transfer rate.

Transfer rate for transferring from PC is pretty much stable at the average rate, however when transferring to PC the performance started at 100 MB/s++ and after 2 minute transferring the rate fall down to about 25 MB/s and the rate is spiking up and down.

I am looking for any solution to this problem because I have tried many things from the Internet and it haven’t worked so far.

Hi BMasayukiW,

Poor or slow performance may be caused by system configuration issues and sometimes due to hard drive. You can run SMART test and Extended Drive test using WD Drive Utilities to check the health of the drive. If drive passes, need to check with the system configuration and refer below mentioned KBA in this concern.
