I want to find out which hard drive in my computer is fastest, so I can put my OS on it. I have tried several utilities that do this in the past. What's a utility that makes this task relatively easy?

I think the free version will only tell you read speed though.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously.
