Agreed. It depends on what you do.
When I ran large-scale Exchange and database systems, we would always get into big fights with the storage people, who believed that SAN disk with performance tiering, replication, etc was the way to solve all problems.
The problem at the time was that the fancy storage cost $40+ Gb/mo and performed like hot garbage because the data didn’t tier well. For email, the “correct” answer in 2010 was local disk or dumb sas arrays with exchange dag.
For databases, the answer was “it depends”. Often it made sense to use the SAN and replication at that layer.
