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...

Do these performance numbers make sense? Correct me if I'm wrong, but aren't these numbers similar to regular IDE drives connected directly to an IDE interface? A SATA drive directly connected to the SATA interface should at least get twice this performance. A decent drive should get 3 times this performance.
Now take 4 of these drives and create a RAID5, it should be screaming above 100MB/s. I don't think gigabit ethernet is the bottle neck here, because I've done benchmarks with gigabit Ethernet and it's way higher than 30MB/s.
So, can someone explain why these numbers are so low? Where's the bottle neck?

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.
