I would try some network benchmarks first (netpipe, netio,
netperf...).  scp will encrypt the data, thus you will not get the
full throughput.

I had problems with Intel e1000 GbE cards last year. Most of the
problems showed up in the kernel log. Keep an eye on the logs.

Then I would test the raid/fs with a benchmark like bonnie++ or 
tiobench.

If both tests are ok, I would use ftp to transfer some files and see
if it behaves similar to samba.
