DISK_PERFORMANCE and Win32_PerfFormattedData_PerfDisk_PhysicalDisk relation

Is there any relation between DISK_PERFORMANCE and Win32_PerfFormattedData_PerfDisk_PhysicalDisk counters?

I have a legacy app that collects disk performance data using IOCTL_DISK_PERFORMANCE but I´m used to use windows perfmon.exe ...

I´m trying to develop an adapter func to translate DISK_PERFORMANCE counters into Win32_PerfFormattedData_PerfDisk_PhysicalDisk. Do you guys know where to find some guidance?
