Recently I’ve bought a My Cloud EX2 and since the installation I’ve been experiencing very (painfully) slow file transfers between the My Cloud and my PCs, as well as between My Cloud and the USB drives attached to it (sometimes I plug in a WD My Passport 2 TB). My setup is as follows:
- WD My Cloud EX2 8 TB in RAID0, latest firmware available installed (1.04.05), factory settings
- Router ASUS RT-AC68U (4x Gigabit Ethernet ports) WD MyCloud EX2 8 TB, connected to the router’s Gigabit port through CAT 5e network cable
- WD My Passport 2 TB, eventually connected to My Cloud’s USB 3.0 port
- Laptop running Windows 8.1, Gigabit Ethernet network adapter, connected to the router via CAT 5e cable (actually, the tests are performed using two different laptops, both from Asus)
In various setups I perceive extremely low file transfer rates between my PCs (all wired to the router, Gigabit ports) and the My Cloud NAS. The maximum transfer rate I get is about 11 MB/s, most of the times averaging 5 MB/s. Even whenever I use the My Cloud web interface to start a backup from WD My Passport 2 TB to My Cloud EX2 (via its USB 3.0 port), the backup operation takes 72 HOURS to complete! (considering the files are being transferred directly via USB to the NAS!)
So I was wondering if this is normal or my My Cloud is having some major issues. Since it has the ability to connect to the router via a Gigabit port (i.e., up to 125 MB/s of file transfer rate) I expected REALLY much more than just 5 or 11 MB/s when transferring my files, which makes me much worried. The network LED behind My Cloud is blinking GREEN, indication a successful Gigabit Ethernet connection to the router.
Below I put the links for some snapshots I’ve made of the tests setup:
- Using the Windows app ‘LAN Speed Test’ I transferred 2 chunks of about 200 MB to the NAS; avg transfer rate (writing): 11.5 MB/s
- Using 2 different PCs to copy the files to My Cloud, using Windows 8.1: the file transfer operations presented strange ripple effects , with the speed ranging from about 11 Mb/s to 0 Mb/s in a “teeth” waveform, resulting in a general average of 11 MB/s.
I must emphasize that the Asus router I’m using is brand-new and it was thoroughly tested with other devices, performing perfectly well (one of the best models available on the market); when I transfer files between the 2 laptops through GbEthernet I perceive about 50 MB/s or more of file transfer rate. I’ve also made the My Cloud tests on a Cisco E1200 (which is not Gigabit Ethernet, though), but the results were always the same: very low speeds, almost zero, with the very same ‘ripple effect’ perceived.
A final remark: today during the day I’ve left the My Cloud to make a copy of my files; at the end of a 12-hour period it had copied about 455 GB , which means a 10.5 MB/s average transfer rate.
Could you please help me clarifying this matter? Thanks a lot!
