WD_BLACK P10 slow read and write speed

I have this drive connected to a USB 3.0 port. I also tried a different USB 3.0 port. My write speed is still just about 50% from the speed which I can see online. I have i3-8100 CPU, 8GB ram. Do you know where is the issue?

Hi @Def,

Please refer to the following link to perform troubleshooting steps: Drive Performance Speed and Benchmarking

What hard drive technology is being used for these drives? SMR, CMR, PMR? This should be disclosed in the product descriptions.

We are sorry for the experience.

We cannot guarantee a particular internal hard drive model, data interface, rotational speed, transfer speed or cache size in the external hard drive enclosure.
