It is unlikely we'd ever see a seek latency of under ~10ms given the synchronization requirements of a CD and the maximum possible rotational velocity. A cache hit would always be faster, even with PIO. Further complicating things, we have to watch the data collection carefully as we're not always going to be on an unloaded system, and we even have to guard against other apps accessing the drive (something that should never happen on purpose, but could happen by accident). As we know in our testing when seeks should never occur, a sudden seek-sized latency popping up in the middle of a collection is an indication that collection is possibly invalid.
