Can you completely snapshot those volumes at any time, recreate them and attach them to new servers? Could you take these snapshots and easily copy them around the world?(again assuming you could snapshot). Are those SSD's automatically replicated to 2 different storage devices behind the scenes to give you near-instant failover? When they go boom are you then driving out to the datacenter to replace them (assuming you have replacements and don't need to wait for them to arrive). Can you do all of this without any upfront cost or excess in capacity??
Probably not. At all.
EBS is NOT harddisks inside a server. Comparing them to such is missing out on all the things that makes it a SERVICE and not disks you buy from Newegg/PCmall/<insert vendor here>. Yes there are disks you can buy to physically put in a server and they are super blazing fast. In fact AWS has those in their i2 instances and they get hundreds of thousands of IOPs as well.
This isn't even comparing apples to oranges, its apples to space monkeys.
