# `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 `mkfs`options 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.
