Hi All, For a project at work I need to be able to write 400MB sequentially to an Ultra-Wide harddisk (Seagate ST32171W 2GB) from an nfs mounted drive as fast a possible. right now we have it down to around 3:45 seconds using the old scsi code. I am using dd with bs=27163 (Approximately = data on one track) to write to /dev/rsd0s2c. Would the cam code improve sequential scsi writes? Also, what sort of general speed improvements has everyone seen using the cam code? I do still plan to test the cam code myself, but I would like to know what other people have experienced.
