2tb MyCloud To 4tb Mirror VERRRRYY SLOW

Hi
I am at the end of my patience now, recently bought a 4tb Mirror, trying to copy over from the 2tb to the 4 via the WD app and copy and past.
The fastest transfer speed I can get is a max of 4 mb a second, hence trying to copy 750 gig it saying time will be Over A Day, its correct 36 hours later it is still trying to transfer over and then it stops !!.
This is going back to the 1980 with the cassette tape coping Atari games over, you put it on in the morning before you went to work and you came home 10 hours later to find that it failed at 97%
Spoke to customer helpline, he said to set it up A to C transfer, tried that idea but as I was doing it a warning came up that I could loose all my data, so that was a waste of time. He also said it was my router not being capable to transfer fast enough, the router is 3 months old, the latest Sky one, spoke to Sky and they assured me it will handle 100mbs.
I also get max of 4mbs using USB 3 from My Passport and that isn’t a router problem !!

Any ideas you kind people before this load of Mirror rubbish is returned?

Thank you in advance

Today we are doing 1000 Mbps not 100. As for my router I have a Linksys WRT 3200ACM.

Are both My Cloud devices connected to the same GIGABIT router on the same local network? Sounds like you are using the slower 10/100mb speed on a router that isn’t Gigabit capable. Have you tried using Windows File Explorer or Mac Finder to initiate the copy/paste? Have you tried using SSH to issue an Rsync command to copy from one device to another?

Are both My Cloud devices connected to the same GIGABIT router on the same local network?

Yes, they are.

Have you tried using Windows File Explorer or Mac Finder to initiate the copy/paste?

When I use Windows File Explorer one of the folders that I know has thousands of pic is empty, but when viewed through WD Access they are all there.

Have you tried using SSH to issue an Rsync command to copy from one device to another?

No not tried that, can’t say that sounds to be a walk in the park, I would possibly struggle with that.

So, which is it? 100Mb or gigabit?

Does your PC also have a gigabit ethernet port?

Have you tried mapping the drives as network shares, and using File Explorer to control the transfer?

That doesn’t sound right. Some problem there.

What specific router model do you have? In your initial post you stated…

You need to know the speed of the network port the My Cloud is connected to on the router. If it really is “100mbs” that is NOT Gigabit Ethernet, that is the slower “fast” Ethernet speed. The other issue is if that 100mbs is the broadband speed and not the local network speed. They typically are two separate values. One is for broadband, one is for the separate local network speed.

This sounds like a separate problem and issue that you will need to provide more information on. Which device (My Cloud or My Cloud Mirror) is missing the files. How were the files copied to the device? Are you using WD sync to sync a computer(s) to the My Cloud device that is missing the files?
