Not off the top of my head, no. The docs used to be very clear about
using 32k raid-5 stripe size for seq and 256k for random ops. And
actively discouraged use of 64k and 128k ( 128k wasent actually even
supported ).

Looking through the 'new' lsi site, some of the content from amcc's site
on these 8xxx and 7xxx sata hba's seem to have been lost ( or I cant
find it anymore ).
