如何编写可以测试磁盘吞吐量的程序？

Question

How can I write a program which can test throughput of disk in Windows systems using c++?

What's the mainly steps and APIs that I can use to programming?

Answer 1

In outline:

• write a known (large) amount of data to disk ( see write() )
• start clock (see time() or clock() )
• read data from disk (see read() )
• stop clock (see above)
• report results (see cout)

Answer 2

One open-source benchmark is bonnie , which mostly uses the standard C API. You'll need to change some of the timing functions to suit Windows.
