I'll second that. I have the 3ware two port model and it seems to have "burped" and decided one of the disks was dead. I went to the management interface (web-only) and removed/added the "bad" drive and then rebuilt the mirror. Performance was fine during the rebuild. Now why the one drive went "bad" is a question I cannot answer... Supposedly the newest firmware supports SMART, but I don't think the FreeBSD driver nor the 3ware web interface do anything with that data.
