EBS

AWS provides multiples services that adjust sizes to your actual usage. This is not really the case when it comes to EBSEBS. You can see EBS has a hard drive that you can attach to a running EC2 instance. The attached EBS will be accessible like any other driver under /dev/xvdX. The idea here, is to provide a way to increase and decrease the size of the used EBS volumes according to the actual usage of the disk, and even allow you to increase the partition size beyond the 1TB limit.
