Post your performance results

Bump, either i'm the "unlucky" one, or other people might be interested by the answer.

And on the other hand, i can't seen to exceed 50-60MB/s with CIFS. Tonight i was curious and ran some tests with the top command running on ssh, and the issue with Dling and SMB CIFS is really frustrating. IOmeter ran at 55MB/s on both read and write. The read speed was very constant with a CPU load under 30%. The write speed was erratic (between 20-30MB/s and 90MB/s averaging 50-55MB/s), which saturates the nas CPU (the SMB process and raid5 process both take turn using the CPU). Where is the restraint on read speed using smb ? FYI, using ftp (with 100-110MB/s read and 60MB/s write), the read speed uses few % of CPU and the write speed also saturates the CPU with proftpd and raid5 processes.

For ReadyNAS Pro 6-200

I found it's interesting that there is no different in performance between stripped x-raid and single disk.

Writing at local level such as copy folder-to-folder (in RAID) and disk-to-disk in AHCI mode the speed is conistent at 75MB/s.

However, transfer over network the write speed gets improved to 120MB/s

From all the tests I see on the internet is SINGLE transaction, one connection at the time of the test. What's been missing is these storage device (SAN) suppose to get connect with multiple servers at any given time.

The speed is max at 160MB/s when there are two network transaction,
single connection max at 120MB/s,
and max Speed at 100MB/s when there is network transfer and local copy at the same time. Here are my test:

1. local copy on original x-raid, folder-to-folder
Write Speed 75MB/s

2. local copy folder-to-folder, and network Write
Write Speed Local 28MB/s
Write Speed From Network 100MB/s

3. Two machines Write to NAS
Write Speed 81MB/s per machine (162MB/s two machine combined).

Did I mention there is no different speed/performance on x-raid stripped VS. single AHCI mode disks ?

I've installed Windows Server 2012 on the ReadyNAS without raid option, each disk is on its own and I get exactly the same result for 3 tests above. What it mean is:

1. speed is depend on how the system handle the load, CPU and Network utilization is high but Memory usage is extremely low
2. type of NIC chipset ( I think this a factor but all NICs, on my laptop my desktop achieve maximum throughput, 980Mbps roughly 122MB/s)
3. type of disk use, Sata III get the result above, Sata II has speed fluctuate lower, for instance local copy of Sata II is about 50MB/s

Given the speed of the ReadyNAS running its own customized Linux VS. Windows OS the speed tests are the same. The clever code that Netgear has been using is catching up by Microsoft with its Storage Space feature in Windows 8 and WS2012. Storage Space feature in latest Windows OS has no intend in competition against ReadyNAS X-RAID but rather aiming at (responds to) the virtualization trend and its storage demand.

Soon, we will see NAS device running Windows OS.

Final though, Netgear (former infratec) is clever in writing a code that allow to add new disks to its existing partition. And it's so good that it allows you to run X-RAID with only 1 disk to start with, unlike RAID-5 3 disks minimum, this is the main reason I bought the ReadyNAS device. I don't like the idea of SAN loaded with DISKs but never use. I've seen too many disks get to replaced before the SAN reach its 70% usage. Even though I bought the ReadyNAS Pro 6 and has 6 drives to use I opt to run only 4 drives and my usage is only 50%.

Your "local" copies sound like copies to the PC then back to the NAS.

Assuming you are not using iSCSI you could SSH in or use something like Ajaxplorer to make true local copies

nope, ssh sesion and doing rsync.

read 50M/s will be quite fine in 1G network.

I need help.
I read post back to Feb 2011 and my head is still spinning at all the configurations.
My RNU6 has been running since May 2011 (see specs below), and I finally had 1 drive fall out (dead, maybe).
I bought new 4TB HD to back up my data before rebuild (plus other HDs in older computers) at 10MB/s for ~7TB of data took a long time.
After rebuild/re sync was done my transfers are still 11 MB/s READ and Write.
I remember getting 60 MB/s when it was new (in 2011,a re sync to 9TB and 3 computers ago).
Don't think I can blame it on D-LINK Gigabit Switch because,
computerHD to computerHD I get ~85 MB/s
computerSSD to ComputerSSD its ~125 MB/s
So Why is the RNU6 only giving me 11 MB/s?

Thanks for your help in advance Kurt

There's your problem.

So, I can not change that setting, it is only a status line, does that mean the RNU6 only has a 100Mb/s nic?
How are other RNU6 owners in the feed getting higher rates of transfer?

Your NAS has a gigabit NIC, but the automatic speed negotiation with your gigabit switch doesn't seem to have worked. I would try a different gigabit switch, or at least try a different CAT6 cable.

I tried a different cat6 cable and port on my D-LINK DGS-1016D Gigabit Switch, still amber or 100Mbits.
I tried a different cat6 cable and tied to Ethernet port2 on RNU6 and still 100Mbit amber on switch.
Rest of the ports on the D-LINK DGS-1016D Gigabit Switch are green for the gigabit Ethernet.
Any Ideas why my RNU6 is at 100Mb ? (specs say 1000Mb)
