Hi,
I received today my WD MyCloud and -excited- wanted to transfer data (bunch of pics) on my WD My Cloud.
Being happy to use this NAS, I started transferring my pictures using rsync… The pictures were on a 5400 WD My Passport Ultra (USB 3.0 - formatted in FAT32).
To my surprise, rsync was quite low. See below :
rsync -r --progress DRIVE_FAT1/2014 /shares/Photo/
sending incremental file list

Been surprised by the low transfer rate, I decided to transfer a bigger file
rsync DRIVE_FAT1/testbigfile.txt /shares/Public/ --progress
testbigfile.txt
732688460 100% 11.17MB/s 0:01:02 (xfer#1, to-check=0/1)
date; cp -rf DRIVE_FAT1/testbigfile.txt /shares/Public/Shared\ Pictures/; date

Mon Jul 14 07:54:53 PDT 2014
19sec so approximately 36.77 MB/s (rsync is 3 times slower, so I guess it’s due to read/write overhead that rsync do)
→ Is it expected to see these transfer rates ? I would have expected more in USB 3.0. WD MyCloud can’t keep up ?
