gp3 as default Amazon EBS volume type

The AL2023 AMI and AL2 both use the XFS file system on the root file system. For AL2023, the mkfsoptions for the root device file system are further optimized for Amazon EC2. AL2023 also supports a number of other file systems that you can use on other volumes to meet your specific requirements.

AL2023 AMIs use Amazon EBS gp3 volumes by default, whereas AL2 AMIs use Amazon EBS gp2 volumes by default. You can change the volume type when you launch an instance.
