性能测试工具允许您体验不同的系统配置，比如 RAID 阵列条带深度和硬盘文件格式，以便了解哪些结果能实现更好的性能。
Performance testing tools let you experiment with different system configurations, such as RAID array stripe size and hard disk file format, to see which combinations result in better performance.
所有这些需求可以通过其他方式加以解决，比通过几个硬盘做RAID配置更昂贵。
All these needs can be addressed by other means, usually more expensive than the RAID configuration of several hard disks.
由于操作系统和硬盘配置有如此多的组合可能，第5节可能对你最有用。
