WDMyCloud (2TB) slow under Windows 10 & some programs can't access files

I did a search here in the forums but couldn’t locate an existing topic for this issue.  Under Windows 10 I have very poor transfer speeds and my multimedia server (Serviio) can no longer access any of the files on the WDMC.  

I have tried Serviio with both a direct network connection and through a Windows share.  Both fail.

Anyone else having Windows 10 issues with the WDMC?

Exactly the same issue with Serviio, and terrible speeds all round

MyCloud EX4   -    4x 2tb drives raid 5

No issues at the moment with Windows 10 Pro and the WD My Cloud. Not using Serviio though. Some CrystalDiskMark numbers from two PC’s on my network. Note: I am not using the original drive in the WD My Cloud enclosure, drive died, using an old 250GB SATA II drive in the My Cloud enclosure at the moment.

On a side note when attempting to run CrystalDiskMark against that same external WD My Passport 320GB USB 2 drive connected to the Desktop Windows 10 Pro PC, the test failed to run and the drive became unstable, would continually disconnect and reconnected every two seconds continuously until drive USB cable was disconnected from desktop PC. Never seen that happen before with this external drive on Windows 10 or Windows 7.

Also see the following link that discusses the copying speed issue with respect to the WD My Cloud.

before you pack up your WD and return it, let’s talk about Copying Speeds!

Thanks for the information.  I’m still uncertain as to the performance to be expected from the WDMC.
