Our test platform differs slightly from the previous version with the inclusion of the Asus A8N-SLI Premium board and the 81.98 video driver set. All drives are tested with NCQ or TCQ off unless otherwise noted. We have added the Samsung SP2504C and Maxtor MaXLine III 7L300S0 drives into our benchmark results for comparison to the Western Digital Raptor series.

    How do you enable/disable NCQ? I can't find anything on that.

    This is accomplished through the NVIDIA SW-IDE driver settings. I will post a how to this evening.

    Thanks, I found it, based on your clue above... I was looking at the drive props, not the IDE controller props... Duh.

    Care to enlighten the rest of us?

    Go to your system props>device manager>SATA controller, and uncheck the option.

    I have the latest Nforce 4 drivers loaded, so I cant say its exactly the same for earlier versions, or Intel/other chipsets, but that would be the logical place to look.

    I am wondering the same thing. Since it seems NCQ is not worth it for desktop use how do you disable it?
  • mlittl3 - Wednesday, February 8, 2006 - link

    This review goes into way too much depth about NCQ vs. no NCQ. I can't remember if they say how to disable it. It is also a great review comparing SCSI vs. Raptor and SATA vs. Raptor performance. It is the most indepth review to date of all raptor drives except it leaves out Raid tests.

    Whoops, I meant to imply that the Storagereview.com review goes into way too much detail about NCQ, not the Anandtech review. :)

    I understood that from your original statement. We wanted to go into more detail but the new game and multi-tasking benchmarks were not ready yet. Hopefully, we can provide more details in the near future.

    Eugene Ra provides excellent information and analysis. :-) We are expanding our test suites at this time and will be providing a more in-depth analysis of drives in the near future. Also, we will be expanding our RAID coverage depending upon the drive being tested (will it make a difference). There is certainly a need to do RAID analysis but it should include more than RAID 0 which only provides benefits in certain benchmarks. ;->
