Thanks Jared.
It is clearer now what they want - to avoid disk hot spots ( group tables by read/write and growth characteristics to avoid hot spots on disk. Disks are SAN, RAID 0+1 - so there is no precise control over file location on disk. Why separate objects into tablespaces/datafiles when you don't know where read/write is going to end up anyway ?
