What gives best performance for running PostgreSQL on EC2? EBS in RAID? PGData on /mnt?

Do you have any preferences or experiences? Main "plus" for running pgsql on EBS is switching from one to another instances. Can this be the reason to be slower that /mnt partition?

PS. im running postgresql 8.4 with datas/size about 50G, amazon ec2 xlarge(64) instance.
