    Your Z68 board supports an SSD assist to the hard drive. Do you have that set up?

    Just a though, use IDE instead of ACHI and no RAID.
    I put the WD drive on the Marvel controller and set it to IDE. Still no dice. Looks like the mere presence of the WD in any SATA port on any controller in any mode is causing the delay.

    Run Western Digital's Diagnostic program on the WD drive.

    I did, and it passed.

    I also updated the bios to the latest version, and still the same problem.

    Short of putting both drives on the Marvell controller (or doing a fresh Windows install, which I'm not interested in doing at the moment), I think I'm about out of options.

    If the SSD runs good alone and the only time you have problems is with both drives attached, it seems to me that there is somthing wrong with the WD drive or the sata controllers on the board.

    I checked my Diagnostics-Performance logs to see whether getting my SSD properly recognized as the system drive made any difference in boot times. That one change seems to have fixed the OtherKernelInitDuration problem but created another, albeit less time consuming, delay in a metric called SessionInitOtherDuration. My total boot time dropped by six seconds in the exchange.

    Anyone care to hazard a guess as to what SessionInitOtherDuration is supposed to be measuring? It increased from 345 to 19358 milliseconds.

    It measures the time it takes winlogon to start, minus smss.exe start time, minus session 0 and session 1 init time. If you take another trace and look at the Boot Phases graph, you should see what I'm talking about.

    Uploading the new Boot Trace report to Rapidshare right now. I'm wondering whether this is some sort of logon related delay.

    Here is my latest Boot Trace report. I don't have the skills necessary to interpret the results, much less formulate an opinion as to what might be causing the high SessionInitOtherDuration reading. Could you help?
