I would like to know if it makes any sense to specify sunit & swidth

I'm asking, because it seems that chunk_size does not matter in a RAID-1
context, nor do stripe units; or do they?
Any tip would be appreciated,

mkfs.xfs will auto-optimize for software-raid arrays for the most part,
with HW raid on a 3ware controller, tweaking mkfs.xfs does not help very
much. with SW raid, at least for raid1 - I use the defaults.
