About The DiskSpd Storage Performance Tool
DiskSpd is a highly customizable I/O load generator tool that can be used to run storage performance tests against files, partitions, or physical disks. DiskSpd can generate a wide variety of disk request patterns for use in analyzing and diagnosing storage performance issues, without running a full end-to-end workload. You can simulate SQL Server I/O activity or more complex, changing access patterns, returning detailed XML output for use in automated results analysis.
Select highlights include:
- Ability to target physical disks in addition to partitions and files
- Variable read/write IO percentage settings
- Custom CPU affinity options
- Consumable XML output option
- Synchronization and tracing functionality
