High Sample rate in collectors

Hello,

We are evaluating using historian in our application. I want to know if it possible to sample at 25kSamples in the collectors or which is the maximum sample rate that i can get form collectors.
Is it possible to have a high sample rate in the collector and a low sample rate in the historian client?
Can be the high sample rate store in the collector for a while in a circular buffer so i can get the last data in case of a event in order to analyze the secuense of the failure? ;)

I hope some one have the answer to my questions.

Best Regards
