Our SAN storage team states that we dont have to worry about RAID 10 or RAID
5 and they will give us the performance we need. They said its RAID 5 and
because they have so many spindles under that RAID 5, it is equivalent to
RAID 10.

Obviously no ones complaining.. I really want to understand, if its
primarily read, are there any major differences between RAID 5 and RAID 10 ?

I take it from a write perspective, RAID 10 is better...

There are many factors that determine the actual throughput of a SAN, not
just the Raid type. If it is primarily read then Raid 5 is just fine for
most applications with a good size write cache on the head. But the only
way to know for sure is to simulate the peak load of your app along with
anything else accessing that SAN at the same time. If the load is light
enough you would probably never know the difference either way on a properly
configured and maintained SAN. It is when the load is heavy that it starts
to become an issue if it has not been properly configured for that load.

A good question for your SAN folks is, what have you been drinking?
