Black 1 TB ( WD1002FAEX) ....very slow write speeds

New drive just out of the wrapper, have tried formatting a couple of time, replaced cable & swapped sata port.

Afaik the write speed should be roughly the same as the read speed.


Hi and welcome to the WD community.

Try running a test using DLG. Check the link below for the steps.

Followed the steps, but step 10: A web page will display the test results for the drive. …web page did not appear, after clicking ‘close’ nothing happened.


But the ‘smart disk information’ shows all green ticks.
