To get the maximum performance out of an EBS volume, it has to be of a maximum size and attached to an EBS-optimized EC2 instance. +- 💸Standard EBS volumes improve IOPS with size. It may make sense for you to simply enlarge a volume instead of paying for better performance explicitly. This can in many cases reduce costs by 2/3. - A standard block size for an EBS volume is 16kb. ### EBS Gotchas and Limitations
