Represents the number of read and write operations a storage device can perform in a second, which is an indicator of the speed of individual operations.
You have the flexibility to adjust the IOPS (Input/Output Operations Per Second) of your storage volume (that will be attached to your EC2) while creating the EC2 instance.
Throughput measures the amount of data that can be transferred to and from the storage device in a given time frame. It's typically measured in megabytes per second (MB/s) or gigabytes per second (GB/s) and is vital for activities like data migration or streaming.
To get a holistic understanding of storage performance, both IOPS and throughput should be considered. Make changes to IOPS and Throughput tailored to your instance needs.
A best practice is to enable encryption for your volume. You can either choose the default AWS KMS (Key Management Service) key or create a custom KMS key for encryption.
