Amazon EBS Throughput Optimized HDD volumes

HDD volumes offering up to 500 MB/s of throughput per volume

Overview

Throughput Optimized HDD (st1) volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. This volume type is a good fit for frequently accessed, large, sequential I/O workloads such as Amazon EMR, ETL, data warehouses, and log processing. Bootable st1 volumes are not supported and we recommend that customers with workloads performing small, random I/O use gp3 volumes. For more information, see Inefficiency of small read/writes on HDD.
