You aren't going to get more than ~100 MB/sec out of a 1G link under
real-world conditions. Granted, going from 72MB/sec to 100 MB/sec is
a 38% improvement, but don't expect anything more. Now, if latency is
the problem, instead of throughput, that's a different issue.
Yep, the overhead is the big factor. You're not going to get much more
than a 20-30% improvement, regardless of the drives you add. I have a
multi-drive flash-cache-backed NAS with a 10Gbit up-link, and from a 1
Gigabit-Ethernet connected client, the fastest I can pull data is 97
MBps over CIFS.
If you really need more speed, I'd recommend upgrading your Drobo and
PCs to have multiple Gigabit Ethernet ports, and bonding together those
ports to create a 2Gbps link for each device.
