I have been using teracopy along with Microsoft Process Explorer to adjust the copying I/O priority.
can we make it a part of the UI itself ?
maybe in the Advanced Options ?
with a check box for Low, Normal, High and Realtime
along with something like Dynamic ( which could be a default ? ) - this will check the number of pending I/O requests and then adjust the priority accordingly to make teracopy not affect other disk operations, maybe even pausing the current operations until there is enough disk bandwidth available.
