Low bandwidth

Hi,

I’m getting too much low speed while reading/writing to myCloud device.

I have a WD MyCloud 3TB device with the latest firmware version installed (v03.04.01-230).

I also checked the discussion raised and solved below:

http://community.wd.com/t5/WD-My-Cloud/Gigabit-router-still-slow-transfer-speed/m-p/627073#M1966

But it seems that it’s not the same case.

I’ve tested bandwidth results in several cases:

  1. WD MyCloud connected to my 100Mbit/s home adsl router. And tested transfer bandwidth through Wi-Fi (802.11g 54Mbits) just near to the router.

  ==> Transfer bandwidth didn’t exceed 20Mbit/s for reading and around ~13Mbit/s for writing.

  1. WD MyCloud connected to the 100Mbit/s port in the router. And tested transfer thgough Lan cable (cat.5) with 100Mbit/s.

 ==> Same results.

  1. WD MyCloud connected directly to my laptop. The interface went up to 1Gbit/s (green light). 

 ==> Same results. Sometimes, the traffic goes till 40 or 45Mbit/s but no more.

Just to note also, that I’ve tested several lan cables (as well as the cable provided with MyCloud), but with no better results.

My question is:

I can understand that the disk in itself, can not handle 1Gbit/s. but, With Wi-Fi I’m expecting to get at least 40Mbit/s as well as through cable going till 100Mbit/s.

Any suggestions on the above?

Thanks alot for your help :slight_smile:

What kind of copy do you use to evaluated the performance? File copy from Windows Explorer to a mapped share, through the WD My Cloud Desktop App, through Wd2go.com?

It’s actually capable of very close to 1 Gbit/sec:

That’s 106 megaBYTES per second, which is very close to 1000 megabits per second if you take “overhead” into account.

You will not get more than 20-30 megabits per second on 802.11g.   Yes, the “theoretical” maximum is 54megabits per second, but that’s under very specific (laboratory) conditions.

Note:  File size can have a large influence on speeds.  The above test is copying several 3 gigabyte+ size files (reading.)

First of all thanks for your replies.

So, for the way how i’ve tested the transfer, I used couple of ways, using basically Filezilla in Windwos.

But also, using scp command from a linux command. and the result is the same.

I can understand scp being slow – there’s encryption overhead, no?

an overhead that makes you loose more than a half capacity?

I don’t think so

Have you tried just using an ordindary share connection?

depends on what ordinary means for you? :smiley:

I don’t trust windows transfer files. Then I’m always using Filezilla as a file transfer client.

I’ve tried it with several other servers locally and it goes to 100Mbit/s easily. But this is not the case with my WD.

This is what is making me crazy. Same infrastructure and same client (my laptop), when I download (same file) from a ubuntu ftp server, it goes up to 90 ~95% of link capacity, but when ftp from the WD, i never went more than 20Mbit/s

Hi all,

Just to update the below:

* I’ve done a full restore of the system. And now I got up to 160 MB/s.

I don’t know what was the problem, but I like my WDMycloud now :slight_smile:

Thanks for your ideas.

Enjoy!
