Yes, I vote this. I think the A+ manuals also make this comparison.

Examining and Tuning Disk Performance

From the first link:

PhysicalDisk\Disk TimeThreshold: Greater than 50 percent, it represents an I/O bottleneck
Significance: Represents the percentage of elapsed time that the selected disk drive was busy servicing read or write requests.

Great links btw, I was wrong!
