I'm trying to compare 2 versions of a backup software product. I setup all IO to go to a dedicated drive.

Is there a way with performance monitor (or anything else) to track the number of IO operations.

I know I can measure disk queue length and different stats like that, but I'd like to know the exact number of IO operations.

  • What operating system?

  • Windows 7, but if needed I could go to Windows 2008 or 2008 R2 Sep 7, 2010 at 18:47
