    HD performance 10k SATA slower than 7200 IDE!!

    I have what seems to me like an odd issue. If anyone can help it would be greatly appreciated. I've been googling all morning trying to figure this one out.

    sda = wd raptor 36gb 10k rpm 8mb cache
    sdb = wd SATA 120gb 7200rpm 8mb cache
    sdc = seagate PATA 160gb 7200rpm 2mb cache

    here are the hdparm infos

    When I run cached and buffered tests, the 10k Sata(sda)drive performs slower than the 7200rpm IDE(sdc).

    The 10k drive has The OS on it, and the other drives are backup. Could this be causing the difference I'm seeing?

    The IDE drive is newer and came out of a **rectTV DVR. What could be the difference there, that makes it perform better than the Raptor? Ares there any settings to change for the Raptor with sdparm to get better performance?

    Here are the test results:

    Re: HD performance 10k SATA slower than 7200 IDE!!

    I'm sorry, I'm not qualified to answer your question, however the one thing which strikes me is the following on your 10k drive (sda):

    Code:
    Standards:
        Supported: 6 5 4 
        Likely used: 8
    I've searched a bit for the precise meaning of this but have been unable to find out anything significant, unfortunately. However I didn't come across any examples where the "Likely used:" wasn't one of the options under "Supported:".
