Correct Answer
False
Explanation
EBS volumes are organized into two main categories: solid-state drives (SSDs) and hard-disk drives (HDDs). SSDs are used for transactional workloads with frequent read/write operations with small I/O size. HDDs are used for large streaming workloads that need high throughput performance. AWS offers two types of each.
