Too slow speeds with Duo V1

The router is netgear cg3000, you can see the specs here http://www.netgear.dk/service-provider/ ... G3100.aspx. You may even notice that the readynas is included in the network picture at the bottom of the page. It should be more than capable to handle a faster speed since It can work with 400mbits.

The 400 mbits speed is referring to the docsis. It should be faster in routing traffic between LAN ports. The reason I asked was to pursue your jumbo-frame comment. Very few routers support jumbo frames. Since the CG3100 doesn't explicitly list them, I'd say it doesn't. So you should probably turn them off in all your equipment. If you want to look into that further, you can test your network MTU with ping.

...However my worry is that the speed is still the same when im conneting the Readynas directly to the computer through a cat-5e cable. By no means it should be slower than USB, and Usb can easily handle 20mb/s?

It should be comparable to USB drives circa 2008, it is not faster. Note this is not just about the network. Your Duo v1 has a sparc processor and 256 mbytes of ram. Your phone probably has a faster CPU.

At this very moment I tried connecting to my 3-year old desktop PC. It has two cards. The 100mbps card could not read more than 10mb/s but the gigabit could easily read with 30. However when writing it could only perform 6mb/s. (this is all wired directly to the Readynas). I really can't see any sense in this :) The macbook has a 1000base-t gigabit card and is limted to 7mb/s.

I suggest using the normal capital letters for megabytes per second.

There are some performance expectations here:

Though in practice it will run slower than those numbers. You don't want to turn journalling off unless you have a UPS connected to the Duo (btw I recommend a UPS with any NAS).

I can't speak for the OSX performance, as I don't have a Mac. Though the Mac universe is quite different now than it was 4 years ago; in particular Apple has totally changed their SMB/CIFS stack. Last time I measured my duo v1 speeds (some years ago) I was getting in the low 20s.

So, you should be getting faster speeds on the Mac and new PC for wired, and you should be getting faster write speeds on the old PC. I would look at the write speed problem on the old PC first. Check the SMART+ stats on both drives (status->health), and look at the network stats (networks->interfaces). You can clear the counts for the network stats before the test on the duo v1 (which is convenient).

I'd also compare the NIC settings on the new PC with the old. Also make sure jumbo frames are off on all devices.
