Since IOmeter doesn't work on mac, my xbench scores are below. The volume is mounted via AFP and the NAS has 512mb ram. Using a gigabit switch with jumbo frames:

Copying 750 MB file over AFP from 2009 Mac Pro to ReadyNAS Pro Business:
With my Macintosh G5, the fastest I could push data to my NAS was about 57 megabytes/second -- which I was pretty pleased about. I just copied a 750 MB file to my NAS, and my Mac Pro topped out at 94 megabytes/second. That's 750 Mbps.
Drag-copied 5.16 GB file over AFP from Mac Pro to ReadyNAS in 53.39 seconds. Activity Monitor topped out at 104.4 MB/sec.
NetGear GS108 switch. Gig-E, no Jumbo frames, MTU 1500. Hardly any performance tweaking on the ReadyNAS Pro except: adding a UPS to turn off journaling, enabled disk write cache, optimize for OSX. RAIDiator 4.2.5, XRAID-2, 3 GB of RAM (4-5-5-15 DDR2). Using only a single Gig-E interface on the ReadyNAS (no teaming). 2009 Mac Pro, 8 GB of RAM, Snow Leopard. Seagate 7200.12 hard drive.
I did a fresh install of Snow Leopard (not an upgrade of Leopard) onto the Mac Pro.
My OCZ Vertex SSD should arrive soon; I'll re-test network speed then.
Since I now have three generations of ReadyNAS, I thought I would post my test results. One key point is that for this system I found that disabling Jumbo Framing on all of the devices, gave the best results. I also found that setting the PC's NIC to maximize network throughput vs. CPU utilization made a significant improvement in overall performance. The cost of this operation resulted in CPU utilization increasing from 10% to 30-44% during testing.

Are people with Windows 7 having the same speed issues I am? Running an IO meter will max my transfer speeds at about 8 MB/s both write and read. Everything seems to be running at gigabit speeds between my computer to the nas. When I switch to XP sp3 I have no issues reaching 29 MB/s.
Is this a Windows 7 issues or what?
Readynas NV+ 4.1.6 firmware
was having the issue with a new build. ended up being Malwarebytes Anti-Malware program holding the speeds down. Turned it off and my speeds went from 5-8MBs to 24-25MBs. Hope this helps.
I have just ordered some Cat 6 cables to replace the 5e cables I'm currently using, so I will re-run the tests and posts the results when that swap out has been completed.
MTU=Jumbo on NX+ and iMac Read = 37.5 MB/s (via FTP and Cyberduck) Write = 140.0 MB/s (via FTP and Cyberduck)
APF Read = 53.47 MB/s, 51.81 MB/s (yes, I don't believe it either, so I repeated it) Write = 25.15 MB/s
CIFS Read = 16.67 MB/s Write = 5.41 MB/s
An interesting note is that once the CIFS copy is finished, the NV+ refuses to disconnect from the share and then becomes unresponsive for about 10 minutes. It eventually recovers, so the lesson here is no CIFS on the Macs. I'm now trying to determine if the slowdown is due to the Mac or the NV+.
EDIT: Slowdown is some interaction between the NV+ and the Mac. The Windows 7 machine is still as peppy as ever. I went back to enabling jumbo frames and everything is good now as long as I avoid CIFS on the Macs.
Model: ReadyNAS Pro Pioneer Edition [X-RAID2] Dual Redundancy Serial: 1YA59CR?x?x?x Firmware: RAIDiator 4.2.9 Memory: 1024 MB [4-5-5-15 DDR2] IP address 1: 192.168.1.111 IP address 2: Not Connected Volume C: Online, X-RAID2, 6 disks, 85% of 7413 GB used
I am running 6 x WD20EARS with jumbo frames and the jumbo does make a difference.
I'm feeling that running XRaid2 with 2 x redundancy might be significantly slower than single redundancy.
I didn't really research as I needed double redundancy and that was that as my budget was limited.... Hmmmm its hard to say limited budget and $3400 in the same breath, but u get what i mean. RNPP 8 x WD20EARS HDD
copying a 7.79 GB (8,370,782,376 bytes) file to the NAS took 5:55 secs or ~=22 MB/s and 1:40 secs from the NAS to the Win7 PC so 77.9MB/sec i.e.~=7790MB/100secs
22.0 MB/s write to NAS 77.9 MB/s read from NAS

More information please? Such as are you in Dual Redundancy mode? What file copy method did you use? CIFS copy? 8Gb file? If i were you i would be very careful and not update the firmware until you have had a good read as 4.2.8 was the last version without pausing and dropout issues.
Has no problems maxing out a gigabit port, consistently see speeds in the 90MB-100MB/s range. The Pro is the real deal thanks to the Core2Duo under the hood.
ReadyNAS NVX here with 4x2TB WD drives. Jumbo frames enabled. single nic. Getting consistently 75Mbps write speeds with AFP from a Mac and 91 Mbps for read speeds.
1gb mem, 4.16 (i think), 4x1000gb, xraid, only cifs, gige LAN with 2 different switches. It's about 91% full that shouldn't affect it right? Jumbo on, all journaling off.
Haven't swapped the cables but doubt that an issue.
I was able to get about 180MB/s sustained with teaming setup on LACP (of course I had to upgrade my switch and buy an intel dual gigabit card that supports LACP) but it was worth it! 🙂
Great story, would be good to see more performance results. Can you run Bonnie++? and also try atto Bench32 in combination with Dataram RAMDisk v3.5 if you want to test your network as well.
•Freeware version (up to 4 GB disk size). Disks larger than 4GB require registration and a license which can be purchased for $9.99 USD. •Universal version for WindowsXP/2000, Vista (32 and 64-bit) Home Basic, Home Premium, Business and Ultimate, Windows Server 2003 Standard, Web and Enterprise Edition •Up to 32 GB disk in Vista and Windows 2003, 2008 Server (registered mode) •Save and load features allow RAMDisk to appear as persistent storage even through reboots •Supports Windows 7
Neither do any better than 16MB/s sustained stream. This is with UPS and all performance switches.
I'm selling these off and going back to system attached storage. The only good Netgear machines are their business ones. The duo was a POS purchased and not built by Netgear has poor support here and does not work very well to my view.
Cost me 750 for two of them. I should have just built a machine for storage but was given the run around by staff who said these POS boxes are good.
