So it sounds that when I got around 73MBytes/second on my iSCSI test doing a backup, that I was getting about the best speed possible. However this was done on a small (4GB) group of fairly large video files. When doing a 650GB+ backup using iSCSI, I got around 48MBytes/second sustained transfer speed to a non-redundant pool over the gigabit switch, and this included a lot of smaller files, as well as large files. Is the 'trunking' similar to ethernet channel bonding? I have 2 gigabit ports on this motherboard (Asus M2N-SLI Deluxe), so I considered looking into using both to give potentially higher throughput for video editing applications.

It's certainly better then the 10 MBytes/s I've seen with 100T Ethernet. Another way to boost the speed is with trunking (802.???ad). You can get gigabit switches that support it for under $400 and Solaris 10 supports it with up to 4 (more?) Gigabit ethernet ports.
