Thanks for the reply. > It's often cheaper and faster to increase the instance storage than move to EBS, prioritized or not. You're saying it may well be cheaper to increase storage in order to get more IOPS than moving to an EBS-optimized instance type? Regarding HA, not relevant for at this point (assuming I understood you correctly). We've only got a single primary and one replica, the latter being used primarily for analytics.
