Hi Folks,Can anyone please let me know the average/typical time taken for

More specifically, time taken for writing a string to a file.
Your question is incomplete and cannot be answered correctly.
Declared average latency for desktop hard drives (see

is about 4 ms. Real performance depends on about a dozen factors.
