Volumes are billed per-second increments, with a 60-seconds minimum period.<br/>
Refer [Amazon EBS pricing]
EBS volumes attached to instances based on the Nitro system are exposed as NVMe devices.
Usage monitoring is available via instance-level metrics on CloudWatch per operations (`EBSReadOps` and `EBSWriteOps`)
and bytes transferred (`EBSReadBytes` and `EBSWriteBytes`).
[Instances built on the AWS Nitro system] (_EBS-Optimized_) are capable of bursting performance.<br/>
`large`, `xlarge`, and `2xlarge` instances provide burst balance metrics to give information about the percentage of I/O
and bytes credits remaining in the respective burst buckets:
- `EBSIOBalance%` monitors the instance's I/O burst bucket.
- `EBSByteBalance%` monitors the instance's byte burst bucket.
Large block workloads usually do not drive enough IOPS to deplete `EBSIOBalance%`, depleting `EBSByteBalance%`
instead.<br/>
Small block workloads usually drive higher IOPS than bytes/second, dropping `EBSIOBalance%` faster than
`EBSByteBalance%`.
Instances can drive EBS burst performance as long as `EBSIOBalance%` and `EBSByteBalance%` are above 0%.<br/>
When the I/O activity is below the baseline rate, the burst buckets refill.
The refill rate for burst buckets is the difference between the baseline rate and the I/O activity.<br/>
In addition, burst buckets are topped off every 24 hours, allowing instances to have burst performance available for at
least 30 minutes per day.
