 - **Incorrect drive configuration**: Using mismatched or incompatible drives within a storage pool can degrade performance.
 - **Incorrect storage space type**: Selecting the wrong resiliency option (such as parity instead of simple or mirror) for the workload.

 Before you start troubleshooting performance issues, consider measuring the system's current performance to establish a baseline. You can use tools such as Performance Monitor or Resource Monitor to collect metrics. You can also use third-party tools such as DiskSpd or CrystalDiskMark to run benchmark tests and gather detailed performance metrics.
