A customer has a legacy application with a large amount of data. The files accessed by the application are approximately 10 GB each, but are rarely accessed.However, when files are accessed, they are retrieved sequentially. The customer is migrating the application to AWS and would like to use Amazon EC2 andAmazon EBS.What is the Least expensive EBS volume type for this use case?
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 large, sequential workloads such as Amazon EMR, ETL, data warehouses, and log processing. Bootable st1 volumes are not supported.Throughput Optimized HDD (st1) volumes, though similar to Cold HDD (sc1) volumes, are designed to support frequently accessed data.This volume type is optimized for workloads involving large, sequential I/O, and we recommend that customers with workloads performing small, random I/O use gp2.https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html
