Disk Controller Performance

With so many storage controllers on the nForce4 SLI boards, we needed a means of comparing performance of the wide variety of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs the World. To refresh your memory, the iPeak test was designed to measure "pure" hard disk performance, and in this case, we kept the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive. We played back Anand's raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's IPEAK utility was then used to play back the trace of all the IO operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance difference to the controllers that we were testing, we used Seagate 7200.7 model SATA and IDE hard drives for all tests.

iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned as it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.

iPeak Business Winstone Hard Disk I/O

iPeak MM Content Creation Hard Disk I/O

It is interesting that the performance patterns hold across both Multimedia Content IO and Business IO, with the on-board NVIDIA SATA 2 providing fastest IO, followed closely by the SiS 180 and Silicon Image 3132 SATA 2 controllers. Please keep in mind that we are testing with SATA 1 drives. In the future, we plan to test with 3Gb/sec SATA 2 drives, which theoretically should have even higher throughput.

The Silicon Image 3114 controller is only a bit slower in MM Content IO, but it quite a bit slower in Business IO. The 3114 does uniquely feature RAID 3 capabilities.

IDE provided the slowest IO performance in this roundup, demonstrating that SATA controllers are finally starting to show a performance edge - at least in IO operations.

We also plan to include IDE RAID and SATA RAID benchmarks in future motherboard tests. Comparing RAID performance on various controllers will definitely be a part of future storage benchmarking and possibly motherboard tests as well as new on-board RAID controllers that are introduced.

    Every single one of these MBs has a fan on the NB... where are the passively cooled mobos? The last thing I want is one or TWO more tiny fans just on the mobo to worry about failing...

    "someof you take Anandtech's word as the word of GOD"

    It's as close as you can get without dying.:)

    Viper - You should come inside the forums for specfic help..

    The article states that the Abit board has a problem with 1:1 overclocking. I disagree. I think the problem is that it does not provide enough ram voltage to run the RAM at high 1:1 FSB. 2.8 volts is not enough to run ANY ram much higher than 280 or so FSB.

    No one wants to help me with my n00b questions :(

    #67 I must be a little a slow …

    In the test “Maximun CPU Clock ( Lower Multiplier )”

    For Chaintec, Abit, etc you use the multiplier in “11”, and only for Epox and DFI you use the multiplier in “9”, then you show a diagram with nothing more than the fsb.
    http://images.anandtech.com/graphs/nf4%20ultra%20r...

    The first question is WHY ?? there is no explanation for use different multiplier in the review. Not some guys, but ALL ones have better result in chaintec and abit with a lower multiplier.

    Thanks Wesley, I did find you had checked HTT, and as I stated in my last post I don't understand what the problem was. But the deeper I looked into the review, the better job you seemed to have done, so sorry if I impied you didn't try very hard.
    DFI has a dual core (beta) bios available, dated 6-23-05
    Epox has a dual core (release) bios available, dated 6-29-05
    These were not used in testing.

    #59 and #60 - One of the first articles I did a couple of years ago about Athlon 64 was how to overclock by manipulating HTT frequencies. I ALWAYS test manual HTT dividers I know should work for certain 1:1 memory clocks as well as Auto HTT if it is an available option.

    #58 - I was very CLEAR in the review that I tested with the BIOS that would allow the X2 A64 to work. We did check each board with an X2. That is the ONLY reason we tested and used very recent Beta BIOS'. Also there are 2 other very recent Chaintech reviews at other websites who had test results almost equal to what I found on the Chaintech, so there are at least 2 other Chaintechs loose with less than stirring overclocking. In the end, as I stated in the review, the Chaintech is a decent board, but at about the same price as the Epox, with poorer overclocking results, it was hard to give it an Editor's Choice this time around. The results found in this roundup should remove anyone's concern that we get cherry boards from manufacturers. I am a good overclocker, and very experienced in air overclocking and memory overclocking. What I got from these boards on air is all they could do with the TCCD memory that is all but standard test memory for motherboards these days. The capabilities of the memory we used is also well known and I tweaked for TCCD if settings were available if the board was not doing well at stock memory settings and our normal test timings.

    I am really pleased some of you experienced better performance than I did with the Chaintech and Abit boards, but I can only report what I actually found in my tests. I don't think you come to AnandTech for a survey of what other websites or Forums found, because I find overclockers are notorious at exagerrating what they can reach with overclocks. We try to provide a consisten test environment for overclocking that will give repeatable overclocking results. Results, of course, always vary board to board, but having said that, OC results are usually pretty consistent on better boards from sample to sample.

    Sorry, wrong link. that one was for the SLI version.

    Foxconn has a BIOS release that allow for multiplier adjustment.
