I have a EMC CX500 with fiber channel drives and slow ata drives. Currently I
have one storage group with all of my users mailboxes residing on the fiber
chanel drives. I was thinking of carving up some data from the slow ata
drives and creating a new storage group.  I thought I could then move some of
my less intensive users from the FC drives to the ATA storage group. I have
always been told that exchange runs terribly on ATA drives but have never
done it myself.  What do you all think, is it worth a try or has it been done
before and does not work at all?

Thanks all,

Chris
