Post your performance results
I thought it might be interesting to see what kind of performance everyone is getting with IO Meter so that we can compare what we're getting. So I thought we could all post our results in this thread...

The NV is definitely the bottleneck here. But if you compare the NV to the competition, you will see that not many are faster(plus these support forums are worlds better than the competition which is why I bought an NV). In time, as NAS devices become more popular, speed will become a bigger factor, but for now it's not to most people.
If you're refering to Buffalo or similar, than yes. I agree. But how about FC RAIDs, like Medea, Infortrend, Xyratec. Granted, these are fiber channel, so they get 280+MB/s with 6 disks. This is about 50MB/s per SATA drive. Which is what I would expect from a SATA RAID system.
But even if we're limited to gigabit Ethernet, I'd expect greater than 30MB/s. So why is the Buffalo/NV/Thecus/etc so slow in comparison? Why aren't they getting similar performance from the SATA drives? Exactly what in the NV is the bottle neck? Is the RAID operations done in software? Is the parity done by the CPU?
Aside from the fiber channel vs. gigabit ethernet, what is different between the Medea/Infortrend vs. Infrant/Buffalo?
