I've got driver/firmware that is about 2months old that certainly helped; prior to that I was getting card timeouts (although I also upgraded the e1000 driver at the same time so it might have been that rather than the 3ware that helped). (Note: I don't expect a driver to perform a dangerous operation like firmware flashing on boot!) > I'm getting a little over 50MB/s when writing to my > RAID volume when completely idle, there's no reason > why you should get less. Well my ~30MB/s is sucking over gig ether and writing in 10MB chunks; but still 50MB/s for RAID5 feels like it sucks. > I'll let you guys know once I try JBOD (as soon as all > the data is moved away).
