Single 136-GB hard drive

Eight 136-GB hard drives. Configuration:

  • C: Single hard drive for operating system and applications

  • D: Single hard drive for Structured Query Language (SQL) logs (.ldf file type)

  • F: Six drives in disk stripe (RAID 0) for SQL data files (.mdf file type)

The performance of the disk subsystem was tested using SQLIO Disk Subsystem Benchmark Tool ( from the Microsoft Download Center. The results of these tests are provided in Large Profile FIM SQLIO Test Results. The information in Appendix A: FIM Disk Subsystem Performance Testing is provided to help you in performing your own disk subsystem tests.


  • The configuration of the server running Microsoft SQL Server® has a significant effect on your test results. Be sure to implement the best practices that are described in the following documents.

  • Although the configurations in the previous table show RAID 0 (disk mirroring) configurations, this was done only to illustrate a configuration from a performance perspective. To protect data in a production network, consider a disk configuration that provides fault tolerance, such as hardware RAID 0+1 (striped mirrored disks).
