I received an email from RightScale earlier today as well claiming this: "EBS is a new Amazon Web Service that provides reliable mountable storage volumes that operate separately from EC2 instances – but at local disk speeds." However, I have not had the opportunity to confirm this just yet. The best solution for optimal performance currently is just to keep as much data cached in RAM as possible, crude but effective. - Justin Rusty,

Mostly because I suspect the IO's per second are orders of magnitude slower then SAN or iSCSI interfaces. Granted, a large number of the database should be in cache, but given how sensitive Databases are to IO performance this seems like a big risk.
