The most important feature is the volume types in those hundred EDS. For example, if you need a volume with high IOPS, you should choose an io2 or io2 Block Express volume type. The default volume type for EBS is GP3, which is a good balance of performance and price for most workloads.

One of the most valuable was snapshots. There were scenarios in which the whole EC2 crashed, or we were unable to use it for some time, but the data on the mounted volumes were crucial to us. So, at that time, snapshots were very helpful.

In Amazon EBS, it is difficult to reduce the space chosen by the customer. The cost increases the moment the size of the storage increases, and I will have to pay for two TB of the tool instead of one TB.

It is hard to access EBS volumes in different Availability Zones (AZs) because most EBS volumes are created in a single AZ.

There is room for improvement in terms of file storage. Recently, we had a scenario in which, in a file share, we had increased the IOPS capacity; this was for the production environment.
