I’ve searched and read every post I can find regarding this problem and tried everything suggested. Here is my situation:
I have three WD NAS drives:
- WD My Cloud 2TB
- WD My Book Live 2TB
- WD My Cloud 4TB
All three drives are connected to the same brand new gigabit switch.
All three drives are connected to the switch with brand new Cat 7 patch cables.
All three drives show green lights on the network jack indicating a GB connection.
All three drives sit right next to each other.
I have tried switching cables, switching ports, rebooting everything, etc. I have verified that all three drives have the most current firmware
I tested all three drives with LAN Speed Test using a 20MB file from a computer connected to the same switch with a Cat 7 cable (it doesn’t even have a wireless card) and here are the results:
Drive 1: Read 506 Mbps Write 170 Mbps
Drive 2: Read 344 Mbps Write 186 Mbps
Drive 3: Read 92 Mbps Write 80 Mbps
These results are repeatable. I have tried writing/reading to different directories, no change. I’ve tried different size files, same relative performance results.
The sad thing is that the two drives that are performing as they should are refurbished drives, the 4TB is not.
Any help would be appreciated.
