Even without that, you are still at the heart of it accessing over a SAN like interface with some sort of local cache. Getting an actual local drive on AWS the performance is night and day

Sure, you can work around it; but it blows up the savings alot of people expect when they don't include this in their math.

Also, SAN is often faster then local disk if you have a local SAN.

How is a SAN faster than a local disk? Any references / recommendations?

Probably comparing a HDD SAN (with data spread across many drives) to a single local HDD.

I would expect by the magic of parallelism?
