How to clear Windows File Cache?

For testing purposed I need to clear file cache (for example to measure file operation performance).


I found CacheSet from sysinternals, but pressing Clear there doesn't help. A file that I just copied to Nil when copied again do this in a blink of an eye (while the initial operation took significant 2 seconds).


Does it mean that HD has its own caching that can't be canceled or cleared?
