Strengths and trade-offs
DiskSpd — where it wins
- Configures random and sequential workloads in detail
- Measures IOPS, latency percentiles, and interval statistics
- Tests files, partitions, and physical devices
Where it doesn't
- Windows is the primary supported platform
- Command-line operation requires technical familiarity
- Results are focused on benchmarking rather than visual reporting
Filebench — where it wins
- Defines custom workloads with its Workload Model Language
- Reports per-operation throughput, IOPS, latency, and histograms
- Supports random, sequential, direct, and synchronous-write testing
Where it doesn't
- Command-line execution requires locally compiled and installed software
- Workload modeling requires defining filesets, processes, threads, and flowops
- Directory platform coverage is limited to Linux
