Yeah, I had read that prior to posting, but let me know if I followed it correctly.  It sounds to me (from the sidebar) that I don't need to do anything because I'm using software RAID and it already operates with 4kB multiples.  Yes?

If so, and I have everything configured correctly, the question then becomes: How does one know if one is getting the most out of their hardware?  I was expecting more like 70-100MB/s writes, and 100-200MB/s reads.
