A company is running a data warehouse and processing large sequential datasets. Which EBS volume would you choose?
For a warehouse processing large sequential datasets, you should choose Throughput Optimized HDD (st1) volume type.
Data warehousing workloads are defined by large, sequential I/O patterns rather than random iops. The st1 volume is specifically engineered by AWS to deliver high throughput (up to 500 MiB/per volume) at low cost for these exact workloads.
