I currently have it set to Active Backup. Since I have WDEX4 hooked up to the gigabit switch using both the primary and secondary gigabit ethernet ports, I have enabled the (Link Aggregation) option however surprisingly, your documentation does not even offer a description about what what each link aggregation option means and the best circumstances to use each one. Is it supported to connect WDEX4 to my desktop directly via usb3.0? If so how do I do it? Can I or must I use both USB ports? Keeping in mind USB 3.0 speed is 60MB/s which would be perfect if wdex4 can actually achieve it. Unfortunately the manual only references using usb to connect other hard drives, nothing about using USB for file transfer from a desktop directly. connect 1 port or both) so that the file transfers are done via dual usb 3.0.

I have looked up the word usb in your full user manual to determine if it is possible to connect wdex4 to my desktop directly via usb and how to go about this (i.e. This is quite useless, I need to have at least 50MB/s for this NAS to be usable. This is when transferring files from my desktop to WDEX4. It starts of at 15-20 then quickly in 30 seconds or so goes down to 10.

While Gigabit Ethernet has a maximum of 125MB/s yet under the non-optimal setup described above, I am only getting a disappointing sustained rate of 10MB/s.

Gigabit switch1 -> Windows 7 Desktop (using gigabit network adapter)

Gigabit router port -> Gigabit switch1 -> WDEX4 (connected using ethernet ports 1 & 2) (Most routers have only 4 ports anyway so it is an unreasonable requirement). Please do not suggest connecting to the router directly since that just isn’t possible. I am unable to connect WDEX4 directly to the router. Unfortunately due to infrastructure reqs. I am running wdex4 NAS with latest firmware (1.05.30) and with 4 WD Red 6TB drives within configured using RAID10 for a total redundant storage of about 12TB. Below is the case request I sent to WD support, I am posting it on the community in case someone here can help.
