Yeah, I forgot to mention the primary/secondary stupid mess. Some chipsets have a primary and secondary port. So primary 2 is after primary 1, then secondary 1 is before secondary 2 (carryover from the primary and secondary IDE drives). I think with those chipsets, the data bus is shared between the primary and secondary just like on the old IDE gear. So access the secondary drive on a bus line will impact performance of the primary drive.<br>
<br>Server systems I use have only primary drives (except for some HP systems who added in the secondary ports that supermicro just leaves off).<br><br><div class="gmail_quote">On Fri, Jun 17, 2011 at 10:28 AM, Gene Poole <span dir="ltr"><<a href="mailto:gene.poole@macys.com">gene.poole@macys.com</a>></span> wrote:<br>

I think I'll get a WD or Samsung going forward.</font>
