AWS STORAGE TYPES / EBS VOLUMES & IOPS
IOPS (Input/Output Operations Per Second) Number of read/write operations a storage device can perform per second. IOPS is used to measure disk performance for: Databases (Oracle, PostgreSQL, MySQL, Aurora) Transaction systems Analytics workloads High-frequency OLTP systems Different IOPS: Standard IOPS (Baseline / General Purpose) Provisioned IOPS (PIOPS) HDD-based volumes Throughput Optimized HDD (st1) for frequently accessed, throughput intensive workloads and The lowest cost Cold HDD (sc1) for less frequently accessed data. st1 volume type is designed to deliver the expected throughput performance 99% of the time and has enough I/O credits * to support a full-volume scan at the burst rate. To maximize the performance of st1, we recommend using EBS-optimized EC2 instances . Volume Type: Throughput Optimized HDD (st1) Short Description: Low cost HDD volume designed for frequently acces...
