Have other folks had good luck with this card? What sorts of configs are you running? I'm in the position of needing more storage, and I'm a bit gun shy on 3ware at the moment...
Does that drive have a jumper to slow it down to 1.5Gb transfer rate? Cheap controllers and drives just cant do it, I have had no end of issues even with *all* my LSI controllers until I jumped all my sata drives down.
As far as performance, it made no impact on my systems.
