I doubt that anyone will successfully argue that SAS drives offer the best IOPS/$ value as long as space, power, and reliability factors may be ignored. However, these sort of enterprise devices exist in order to allow enterprises to meet critical business demands which are otherwise not possible to be met. There are situations where space, power, and cooling are limited and the cost of the equipment is less of an issue since the space, power, and cooling cost more than the equipment.
