Abstract
A data storage system may include one or more storage arrays. Each storage array may include a first set of solid-state drives and a first set of striped hard disk drives. Each solid-state drive of the first set of solid-state drives has a first data throughput and the set of stripe hard disk drives has a second data throughput. The second data throughput of the first set of striped hard disk drives is within a threshold throughput of the first data throughput. The data storage system also includes a processing device configured to receive an access request to write first data to the storage array and determine a read access frequency of the first data. The processing device may also be configured to determine a write access frequency of the first data and write the first data to the first set of solid-state drives or the first set of striped hard disk drives, based on the read access frequency and the write access frequency.
