Oh I see. I will reformat and set sunit/swidth for my current 3 disk raid5 (2 data disks). What if I later add a 4th disk (3 data disks), would using the mount option to specify the new swidth have any performance hit? I assume old files might work slower but any new data that is written would be aligned across all the drives? Or should I just reformat again at that point?
