Given that your company operates a global search engine with a large disk farm, does upgrading to either RAID 0 or RAID 1 make economic sense given that your income model is based on the number of advertisements served?

For disks in the table in Exercise 6.18, assume that your vendor offers a RAID 0 configuration that will increase storage system throughput by 70% and a RAID 1 configuration that will drop AFR of disk pairs by 2. Assume that the cost of each solution is 1.6 times the original solution cost.

Measurements and statistics provided by storage vendors must be carefully interpreted to gain meaningful predictions about their system behavior. The following table provides data for various disk drives.
