Benchmarks: NAS Performance Toolkit
Intel's NAS Performance Toolkit simulates various workloads to gauge theoretical performance. Content Creation is primarily a test of random writes, Office Productivity is a read and write test involving hundreds of small files, Directory Copy from NAS is a read test that uses 2,833 files, while Photo Album is a largely sequential test of mixed-sized reads.
SSD caching clearly doesn't benefit all workloads. We see a performance increase of 20 per cent in some scenarios, others show barely any benefit and certain workloads see a small performance dip.
