        By usage, I assume you mean %busy?  My usage is roughly 4% on each
drive. Although, this is probably so low due to the lack of heavy
processing right now. I just added another 30Gig DASD bringing me to a
total of 60Gig.  All disks are in a RAID5 array.  My original 16 are 2Gb
each, the new drives (8 of them) are 4Gb.  It looks like the data is
still being written to the new disks...half are at 90%, the others at
30%.  Will this have an big effect on my processing?
