D5-300 is glacially slow

If you are sure you got a wrong delivery, please contact the service team for after sales service. Just find the email address from my signature.

To clarify, it was not a wrong delivery, but a wrong purchase, when purchased the two models are indistinguishable if not for the "C", that at the time did not seem to have any importance.

As I know now, the difference instead is significant.

I wish TerraMaster were more helpful.
Despite the name, it is a Chinese company, isn't it?

If you are sure you followed all steps in the troubleshooting guide and the issue still persist, then you can contact the service team for warranty service.
12MB/s is far away from the normal speed value.

Hi!

I just joined the forum because I am having this problem too - my D5-300C suddenly becoming super-slow and occasionally almost non responsive.

I have had this device set up for approx 1 year with no problems until now. I am on a 2017 imac running Ventura 13.4. Also of note - it is my first major external drive set up and I am not very well educated on the tech aspects of the setup - other than when I set it up it worked well and now it's crazy slow. If someone could please help me step-by-step with some possible solutions I'd be really grateful

Thank you.

Thanks @TMroy

I read the link and don't suspect any hardware failures. Plus I have not changed cords etc.
What else might you suggest?

Kindest, Amber
