Amazon OpenSearch Service now supports Amazon Elastic Block Store (Amazon EBS) volume type gp3 (General Purpose SSD), in addition to the existing gp2, Magnetic and PIOPS (io1) volumes. You can use gp3 volumes on our latest generation T3, R5, R6g, M5, M6g, C5 and C6g instance families. Amazon EBS gp3 enables customers to provision performance independent of storage capacity, provides better baseline performance, at a 9.6% lower price point per GB than existing gp2 volumes on OpenSearch Service. In addition, with gp3 you now get denser storage on R5, R6g, M5, M6g instance families, which can help you to further optimize your costs.
Customers can scale IOPS (input/output operations per second) and throughput without needing to provision additional block storage capacity, and pay only for the resources that they need. gp3 volumes deliver a baseline performance of 3,000 IOPS and 125MB/s throughput at any volume size. In addition, OpenSearch Service provisions additional IOPS and throughput for higher volumes for optimal performance. For use cases where the application needs more performance than the baseline, you can scale up to 16,000 IOPS and 1,000 MB/s throughput for an additional fee. With this release, we have also increased the maximum volume size supported per instance for gp3 by 100% when compared with gp2 for R5, R6g, M5, M6g instance families.
