Ciao.I have a Readynas Ultra 2 with 2x WD RED 3 TB.I used to have the HDs in a Raid 0 configuration... but few days ago without warning I have lost everything.My previous configuration was the Ultra attached to a Wifi AC router and the PC connected via wifi AC with the router.The comunication speed between PC and NAS (via wifi) was about 50 MB/s.Now I have reistalled the OS, did a factory reset and even tested the HDs on a PC to make sure they were fine.I have now a Raid 1 configuration but I am soffering an issue with speed.It seems that the LAN connections of the NAS have a problem. I am getting poor performance via 1 Gbps LAN.On Direct to PC connection via LAN, I get 15 MB/s that immediately drop to zero.I have tryed both with Jumpo on and off (both on PC and NAS) and the situation doesn't change.The Cable is CAT 7.Ethernet are: Intel(R) 82579V Gigabit Network Connection and Realtek PCIe GBE Family Controller,Please help!

After changing parameters (jumbo off) now I have 80 MB/S for few seconds then drop to zero.The Static IP config is:NASIP 192.168.168.1Subnet mask: 255.255.255.0Gateway nonePCIP 192.168.168.60Subnet mask: 255.255.255.0Gateway 192.168.168.1Wifi is on:IP 192.168.1.50Subnet mask: 255.255.255.0Gateway 192.168.168.1.1Is that correct?

Not exactly.If your wifi router is 192.168.1.50, then your other LAN devices would normally have IP addresses in the format 192.168.1.x. Your gateway is not the wifi router, or is it?Perhaps if the gateway is really 192.168.168.1, then setup your whole LAN like that, with IP address as 192.168.168.x.Having said that, you have setup a direct PC to nas connection so this would appear to rule out the IP addresses or wifi being the problem. How did you test the drives?What firmware is on the nas?

Thanks for the reply!I did the test with just a drag and drop file from one folder to the other as I am used to do.The MB/S figures are the one that Windows display while copying.I use Win 8.1 by the way.The firmware is the latest 4.2.27.Sorry for that unnecesary confusing line about wifi is on...I have intetionally used other numbers than the one that my normal network has to avoid conflictions.In normal configuration, my Wifi router has 192.168.1.1 with DHCT disabled and all other components have static IP.The PC is 192.168.1.50 while the NAS, when normaly connected to the router via Giga LAN, is 192.168.1.100.Here I have connected the NAS directly to the PC but I have also isolated the PC from the Wifi disabling the wifi card.So I gave them 192.168.168.1 to the NAS and 192.168.168.60 to the PC.I am not sure what number should I put as Gateway on the PC (since is mandatory) since no other hardware then the NAS is connected.I hope I was more cleare this time.Thanks again for your help... do yo know what else should I try to do to fix the problem?

You can use 192.168.168.1 for the gateway on the PC as well.

Thanks StephenB!So this is what I did today:I have used two different LAN Cat 7 cables to make sure those were not the problem.I have disable all other comunication cards on the PC (wifi/Bluetooth/ unused LAN).Jumbo disable.MTU onthe NAS set on 1500 then to 1472 with no changes in performances.First attempt.I have connectet NAS LAN Port 1 with Realtek PCIe GBE Family Controller of the PC.Configuration:NASIP 192.168.168.1Subnet mask: 255.255.255.0Gateway 192.168.168.2 (the PC address)PCIP 192.168.168.2Subnet mask: 255.255.255.0Gateway 192.168.168.1 (The NAS address)Result:Moving a 4 GB file with drag and drop: 90 MB/s for 3s", then drop to 0 MB/s, then raise to 20 MB/s for 2"s, then drop to zero...then stuck at 512 kb/s..Second attempt:I have connectet NAS LAN Port 2 with Intel(R) 82579V Gigabit Network Controller of the PC.Configuration:NASIP 192.168.168.100Subnet mask: 255.255.255.0Gateway 192.168.168.50 (the PC address)PCIP 192.168.168.50Subnet mask: 255.255.255.0Gateway 192.168.168.100 (The NAS address)Result:As before. Start at 83 MB/s, drop to 0 then raise and drop, with the highest peek at 2.78 Mb/s, lowest 0. Ii seems to be stuck most all the rimeLast attempt:I have connectet a Surface Pro with a Giga LAN adapter to the NAS Port 2.I gave the Surface the same configuration that the PC had. Result:Start at 83 MB/s then drop to 0...So I am sure the problem is not the PC or the cable.Please tell me if there is any other config attempt I should try.I have already done 2 factory reset and I have overwrite the firmware once.One sidebar question: as I have formatted and reinstalled everything in a Raid 1 configuration, now it showing me that 1% of the free space ( 47 GB) is already taken (not by me). Is that normal?Thank you in advance!

Not sure how to do it.. you mean disable the "VLAN" in the NIC prorpieties?

Are you using VLAN???

I was thinking more about interrupt moderation, send offload, checksum offloads, and adaptive interframe spacing.

...ehm...no!
It was the only funky name in the NIC propriety that Google related to hardware acceleration.
So no, I am not using VLAN, but its listed as 'enabled' in the propriety by default.

Good news!
The second HD did not survive to the second batch of WD test I just did tonight..
I have run once the test and it did found some surface errors. It propted me to fix it, I reply yes and that was the last time I have comunicate with HD 2 (RIP).
The SMART still display it green but the WD Test now won't even start ("too many errors found").
No way to format it or anything.
Cerimony will be held when WD will send someone to pick it up (I hope).

Hi.

The second disk is dead.
The first one is in great shape, it did pass all the WD software tests.
Therefore there most be something wrong in the NAS that in limiting my lan comunication speed to 35 MB/s...
Any idea?

How full is the disk? Transfer speed does vary across the surface (there's a graph here: http://www.tomshardware.com/reviews/red ... 248-2.html).

Seems unlikely, but it doesn't appear to be the network or the NAS itself.

...the Disk is blank. I did a factory reset. Now only few GBs ARE taken from the system itself.

I did the test with two different LAN CAT 7 cables, with the two different Ethrnet controllers (Intel 82579V Gigabit Network Connection and Realtek PCIe GBE Family Controller) installed on my Desktop PC and also with a LAN/USB3 adapter connected to my Surface PRO.
Same results.

Sometimes performance increases with RAID, but it seems to me that the ultra should be doing better with jbod.

Are you comfortable with ssh?

Well.. confortable is a big word..
Tell me what command I should sent and I let you know if I managed to do it.

Just thinking you could try copying a large file to /dev/null via ssh, which would give you a direct measure of the disk throughput.

Ok I will try.

Two questions first.
I have installed OS6 to see if the speed was improving (no!) then root back now to OS4.
Which one you suggest for ReadyNAS Ultra 2?

WD is sending me a new HD but they run out of the exact same one as mine.
They are proposing me a different revision of the same hd, the WD30EFRX-68EUZN0, that according to internet is suffering an "Idle3 bug" (LCC value increasing).
Suggestions?

Thank you so much again!
