Thanks for the suggestion -- the card I picked up (also a SilImg 680)
cost me $20USB *including* $5USB shipping and is sold under the "Syba"
brand.

Indeed in my case it appears to be. I've now copied all the data from one
disk to the other a few times, set up RAIDFrame to mirror the two drives on
the SilImg680 controller and performed a few reconstructions (to initially
populate the second drive and then to test failure recovery by marking one
of the components as failed and then reconstructing). The current recon-
struction is plodding away with vmstat claiming 25MB/s from both disks.
The issue with the Promise definitely seems to be specific to that card or
line of cards and it *does* look like some sort of bug in our drivers.
Anyway, the key is that I'n now up and running and happy.
Thanks for the hints,
