Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

I've got a DNS 343 4x 1.5TB WD15EADS-00P8B0 (WD Caviar Green) FunPlugged
The whole thing is terribly slow, when copying from the network it'll run at around 30% GIGABIT for a while, then it just drops out and the network monitor shows a spiky graph, mainly no transfer with intermittent bursts of transfer.
I removed everything and hooked it directly into my spare LAN port. Same thing happens, changed cables etc. etc.
Also, sometimes when I reboot I have to endure a 24 hour re-sync. I've tried disabling fun_plug - it made no difference, now I'm having to resync again, so cant test a local CP.
Did anybody have this issue at any point?
What's the command I need to monitor each drive's SMART data for things like the head parking count, or just to identify which drive could be the problem?
EDIT: Also, is there anyway to PAUSE md0_resync? - so i can just test for a while then continue it later?

Hi. I have a similar situation here: same 1.5TB drives (WD15EADS-00P8B0 WD Caviar Green) in a DNS-323 RAID 1 config. Static IP and original v1.07 firmware (no funplug). Auto-speed to a gigabit switch (should I use 1000 instead?).
Very slow! And seems to burst transfer data, not a regular flow. I have 6 other DNS-323 with 1TB Seagate drives on the same switch; never experienced this before.
I just enabled Jumbo Frame and set it to MTU = 9000. It was disabled before. Will report.
Let's keep posted on this please. Fingers crossed. Iam Nemo

I just enabled Jumbo Frame and set it to MTU = 9000 and it seems to be MUCH better.
I will continue posting on this thread from now on : http://dns323.kood.org/forum/viewtopic.php?pid=33721

I had crappy throughput until I turned on Jumbo frames.
Keep in mind the Ethernet switch has to support it too!!
In any case, I'm happy with the 318Mb/s I get out of windows.
I have another computer with a different NIC and it never gets over 100Mb/s -- I have no idea why.
RealTek NIC w/AMD 9950BE Quad core and 4GB. You'd think that's be enough CPU push.
But the other box is a P4-3Ghz w/1GB of RAM on Intel PR01000 MT. Go figure.

Hi Ben. Well finally the improvement was short term. My switch does support jumbo frames (but at what MTU I don't know) and so does my main PC but it has never been implemented in the Nvidia driver (!). So I'm back at mid-level transfer speeds, not too bad.
