I have had the 3TB MyCloud for about 5 months and was dissapointed with the transfer speeds.
In that time I changed from an Asus RT66AC to and Asus RT87AC, have used a succession of Cat 5e and Cat 6 cables and only use HP Procurve Switches. The network is gigabit throughout
However despite this I was getting write speeds of about 10-11 Megabytes per second and read speeds of 17-18 Megabytes per second.
I SSH’d into the MyCloud and saw a moderate increase by switching off the background thumbnail tasks.
I turned off Media serving (both DLNA and iTunes).
Still couldn’t get the kind of speeds I expected.
My Qnap TS251 can read and write at over 100Megaytes per Second on same network).
I had assigned the WD a fixed IP in router, port forwarding was correctly set up but still poor transfers.
I then read this http://www.zdnet.com/article/mavericks-smb2-problem-and-fixes/
Today I tried connecting the shares via SMB instead of AFP and it started hitting 35 Megabytes per second (writing)
Directories seemed to load faster in Pathfinder too.
So if you have a Mac and are frustrated by slow file transfers, try using SMB instead of AFP. It may just work.
