dear Wd support
hello, i have issue with my cloud its to slow to transfer file its been 3/MB -7/MB
and i connect External hard drive directly to the device
126 GB going 7 hours to transfer
i dont know why and, all devises connected locally through Ethernet
what color is the network LED on the back?
Green == gigabit
Yellow == 100mbit
If the LED is flashing Yellow with activity, then the 7mb/sec rate is about your top speed, because the switch/router you plugged it into cannot transfer data faster than that.

dear friend
thanks for your fast reply
its blinking yellow
can you tell me the best solution ??
its from cable
or router
or laptop
please advise and offer best solution
best regards
Check energy settings in the router menue - some have a “green mode” for lan which means only 100 mbit.
Ceck/replace you LAN-Cable.
Try to connect the external hard drive to your desktop/laptop.
@nogood what is the best cable to use??
Cat6e.
But I doubt the cable type is the problem. More than likely, your switch or router cannot do better than 100mbit.
Remember, there are 8 bits in a byte, so divide whatver speed your transport layer is by 8, to get the theoretical top speed in bytes. Remember that this theoretical top speed does not have any protocol overhead figured in. You will find that 100mbit comes out to 12mbyte theoretical. You can easily take 2 to 4mb/sec off the top for background traffic for the protocol. That leaves you with the ~8mb/sec you are reporting as your top speed. Switching to gigabit hardware will increase that to nearly 100mbyte/sec. It is strongly suggested. 
@Wierd_w dear just need to confrim what you mean about switching hardware to gigabit the modem or what??
We’re not WD Support: this is a user-to-user forum
Although it is a USB3 compliant interface, the USB HDD interface on the MyCloud cannot support the sustained data transfer rate suggested by the USB3 spec, as you have found. It is only compliant at signal level, and burst data transfers.
For large transfers, the User Manual recommends connecting the USB HDD to a PC, and copying data to/from the MyCloud over a local gigabit ethernet network.
@Wierd_w @cpt_paranoia this the light from the device but the speed only 4/mb to 6/mb
it’s green right?
i use cat7 cable
the router is huawei mini router support cat6
Is the data you are transferring being hosted by the USB drive, or is it from the internal HDD of the Mycloud?
Don’t know if its been asked yet but from where to where are you copying data? From a computer to the My Cloud internal hard drive? Or from a computer to a USB hard drive attached to the My Cloud?
As indicated above if copying to a USB hard drive attached to the My Cloud you will NOT get USB 3.0 advertised speeds. And this assumes one is using a USB 3.0 external USB drive.
It also helps to use a dedicated disk testing program to give consistent results. Using Crystal Disk Mark (http://crystalmark.info/software/CrystalDiskMark/index-e.html) here is the transfer speed from a wired Gigabit Windows 10 PC to a mapped Toshiba USB 3.0 external hard drive attached to the USB 3.0 port on a first generation My Cloud.
If you are only getting 3 to 7 MB/s transfer speed that may indicate using a USB 2.0 drive or the My Cloud USB port improperly reading the port speed of the attached USB drive. In any case if you use the forum search feature, magnifying glass icon upper right, and search for USB speed you will find the slow speed of the My Cloud USB 3.0 port is a common complaint.
If I understand this right you are saying you have connected the USB drive to the PC and get the same speeds as you get when the USB drive is connected to the My Cloud. Is this correct?
What is the make/model of the USB drive? Is the USB drive a USB 3.0 drive? Does the computer you connected the USB drive have a USB 3.0 port?
@Bennor yes you right
pc and the hard drive are supported usb3.0
What is the brand/model of the USB drive?
If you are getting the same transfer speeds to the USB drive when it is connected to your computer (not the My Cloud) that would potentially indicate a problem with the USB drive itself or with the USB cable being used, which is why it would help if you post the brand/model of the USB drive.
@Bennor no issue with usb 3.0 because transfer localy from pc to hard drive over usb3.0 is getting 42 mb/sec
the brand is WD HDD
This is just musing out loud… but I wonder how much of these slow transfers are due to filesystem driver, and how much are due to bad port reference design.
Previously you appeared to indicate you were having slow speed issues BOTH the computer and the My Cloud when you had the USB hard drive attached to either the computer or the My Cloud. Is this not the case? Are you now saying that the USB hard drive performs significantly faster when connected to the computer?
Not sure it has been asked but are you using Gigabit wired networking (including using a router that supports Gigabit) between the computer and the My Cloud? How is the network configured? Is the computer using WiFi? If so what is the WiFi speed?
If the computer is connected via Ethernet wire to the router, what is the computer network port’s speed? 100 Mb or 1 Gb?
How are you copying the files from the My Cloud to the USB drive? Using Windows File Explorer or Mac Finder? As a troubleshooting step have you tried using a mobile device with the WD My Cloud app installed to copy the files from the My Cloud to the USB drive Share on the My Cloud?
@Bennor @Wierd_w last question
the transfer its does relay on the speed of the internet from the ISP?
For data transfers between computer and MyCloud within your local intranet, your ISP internet connection speed has no bearing on the transfer rate at all; local network transfers do not use the internet.
The only time your internet connection speed has any bearing on data transfer rate is if you are accessing the MyCloud remotely, from the internet.
