Why put logs away from rootdbs?

What are the reasons why Informix keeps on about moving your logical and physical logs away from rootdbs? Surely if the whole instance is going into a single RAID 1+0 array it doesn't make any difference? OK, a bit more to glean from onstat -D perhaps, but is there any other benefit? In a rare break with tradition for me, this is a REAL, IN-USE email address. Andy Kent

If you're on 9.40 you could put it all in one chunk.
