I think there are optimal situations where any configuration looks good . . How often can a real-world disk actually deliver the 6Gbs when only a minority of disk reads are long sequential runs on the platters? none of hard drives can saturate 1.5Gb/s

there is more than the connection speed 6Gbsdo not help you much as long the physical disk can not write in this speed and more concurretn writes making this worser - so there are many things like big battery backed caches fon a SAN which are imprtant for OVERALL performance with cache as big

is random seek latency. And the faster the spindle, the lower the latency. Thus 15k Seagate SAS drives are excellent candidates for mail store duty, as are any 10k or 15k drives. definitely not counting by $/IOPS rate. even worse looking with $/GB which is more important unless you make 1GB
