I also saw somewhere (may have been twitter) that the reads they benchmark
against for provisioned IOPS is something like 4KB or 8KB. It was something
small, smaller than the page size memmapping will use anyway.

http://www.mail-archive.com/user@cassandra.apache.org/msg11022.html sums it up

EBS is like a giant SAN which will drop out at any second,
I strongly recommend against EBS, even with optimized & ebs provisioned. The
throughput you'll get from local drives is significantly better than what
you'll get with EBS (even 4K iops provisioned)
