This document summarizes an assessment of SSD performance in the IBM DS8000 storage system. SSDs provide significantly higher throughput and lower response times than HDDs for random I/O workloads. Testing showed SSD response times were much lower than HDDs across all data points. Using SSDs can improve performance for applications requiring low response times while reducing energy usage, cooling needs, and data center footprint. SSD best practices include placing hot data on SSDs and using SSDs for applications that traditionally overprovisioned HDDs.
