If the business (like for example insurance) acquires lots of data continually then the cost of downtime due to a disc failure is huge compared with the extra dollars for RAID with Hotswap.
Likewise for all customer-facing services. People get cranky—rightfully so—when they can't get the services you promise. They're especially irate when they're paying for those services.

Redundancy is the _only_ way to provide high reliability services.
