<pre wrap="">You may get more meaningful results with a better description of what you're actually looking for:

That being said, I'll just asume that

Good point Martin. While this is a generic discussion, personally I am
looking for a backend system and I'll be recording as many streams as I
can from a number of capture cards. I think this and your other
assumptions are correct.<br>

Do you put any stock in this metric for non-desktop drives (like
DVR-specific drives)?<br>

Interesting. Any idea what a typical CPU overhead might be for a
typical soft raid option?<br>

Thanks again Martin!<br>
