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? – brent Sep 7 '10 at 18:46
Windows 7, but if needed I could go to Windows 2008 or 2008 R2 – Brian R. Bondy Sep 7 '10 at 18:47

The metric you are looking for is "Disk Transfers/sec" under "Physical Disk" in Performance Monitor. Screen-capture of PerfMon setting
