I purchased a WD My Cloud EX2, 4 TB (NAS) last month. It has been performing satisfactorily on my gigabit network in RAID 1 (Mirror) mode EXCEPT for the transfer speed when COPYING data from the NAS to a 3.0 external USB drive plugged directly into the NAS USB Port. I have tried both using the windows network AND the BACKUP function in the WD supplied browser application. They both give the same SLOW result (28 MBytes / Sec). My firmware version is 1.05.21.
I opened a support case, but WD’s first response appears to be nothing more than a stock answer to reset the system, update the firmware and do the tests. Apparently I have to go through those before they’ll actually respond directly to the issue I’m having. IMHO, the problem with handling support in that manner could introduce new problems having nothing to do with the original issue. In fact, according to many in this forum, updating the firmware may be asking for more problems.
In going through some of the WD product support suggestions for - whatever they mean by - “large file transfers”, WD appears to recommend plugging the External USB 3.0 drive into the PC rather than directly into the NAS USB 3.0 port. That seems strange, but I’ll give it a try on the weekend and report back to the forum.
Meanwhile, has anyone experienced the relatively slow USB 3.0 transfer I related above and, if so, has initiating a copy from NAS to USB Drive when the USB 3.0 drive is directly connected to the initiating PC’s USB 3.0 port resolved the transfer speed issue ?
Just as a reference, the transfer speed when COPYING data from a Windows 7 PC to the External USB 3.0 Drive attached to that PC (NAS not involved) is approx. 87 MBytes per second. The transfer speed when copying data directly from the NAS to the Drive (when connected directly to the NAS USB port) is ONLY 28 MBytes per second. The data is made up of 8 total files, two 8 gig files and 6 others for a total of 18.4 gigabytes.
Thanks for your help !!
