Which is faster for read access on an EC2 instance; the "local" drive or an attached EBS volume?

I have some data that needs to be persisted so have placed this on an EBS volume. I'm using OpenSolaris, so this volume has been attached as a ZFS pool. However, I have a large chunk of EC2 disk space that's going to go unused, so I'm considering re-purposing this as a ZFS cache volume but I don't want to do this if the disk access is going to be slower than that of the EBS volume as it would potentially have a detrimental effect.
