My test pool is a mirror w/ two sata2 1TB drives attached via esata; attached to my hackintosh via a sonnet pro express card (marvell chipset) w/ pcie<->pci express adapter. This is a sans digital drive tower with 2x silicon image port replicator boards inside. I'm splitting my mirrors between the two replicators and esata channels.

On single drive HFS these drives do 90-110 MB/s read and write.

On the 2 drive ZFS mirror I am getting an average of 65-75 write and 70-95 MB/s read.

AJA System test shows write 78MB/s and 125MB/s read for 1GB files.

I added a second mirror of 1TB drives to the pool; essentially with the mirroring of drives taking place between drives my two port replicator boards. My AJA benchmarks are 92MB/S Write and 169MB/s Read for a 1GB file.
