The File System Performance Test measures the performance of a file system driver (FSD) that uses the Microsoft Win32® application programming interface. You can use this test to obtain throughput metrics for various file system usage scenarios on a storage device block driver that runs under the FAT, ExFAT, TexFAT, or a custom FSD. The test can also measure the performance of the Object Store file system.
To judge the performance data produced by this test, you need a basis for comparison. For instance, you might use a known theoretical throughput maximum for a specific storage device, or you might compare two data sets obtained by running this test on two different devices, FSDs, or block drivers. The following are examples of useful applications of the File System Performance Test:
- Comparing file system I/O to block driver I/O (the latter can be obtained by running the Storage Device Block Driver Performance Test).
- Comparing file system performance on storage devices from different manufacturers.
- Running performance test every time there is a known change in any of the underlying components in the file system stack.
