AFAIK if the average size of an I/O operation as long as the corresponding
variance are low... go for a single RAID10,f2 with a stripe size slightly
superior to this average. This way you will have most requests mobilizing only a
single spindle and all your spindles acting in parallel. If this average size
varies upon tables one may create a RAID (with the adequate stripe size) per
database partition.
