Disk Controller Performance

With the variety of disk drive benchmarks available, we needed a means of comparing the true performance of the wide selection of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs. the World. 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 file of all IO operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance differences to the controllers that we were testing, we used the Maxtor MaXLine III 7L300S0 300GB 7200 RPM SATA drive in all tests . The drive was formatted before each test run and a composite average of 5 tests on each controller interface was tabulated in order to ensure consistency in the benchmark.

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

The performance patterns hold steady across both Multimedia Content IO and Business IO, with the ULi based disk controllers providing the fastest IO operations followed by the on-board NVIDIA nForce4 SATA controllers. Of particular note is the excellent performance generated by the ULi IDE controller logic while the SATA performance is incredible compared to the nForce4 chipset.

    I thought so, but I wanted to make sure. That's great. So this board is pretty much a good overclocking board for a great price. I'm hooked.

    When released the "J " version of this board sports both Gb Ethernet and 8 Channel ALC850 Audio. Look for the EPoX EP-9U1697GLI-J ... I'm definitely getting this mobo.

    We still do not have confirmation if this model will be released in the US. We certainly have expressed our feelings to EPoX that this is the model that should be offered here. Also, the ALC-850 is not real upgrade from a quality of audio output aspect compared to the ALC-655. We lobbied for the ALC-883 as the cost differential is minimal compared to the ALC-850 but EPoX is betting most people buying the board will upgrade the audio for gaming anyway. We think the ALC-883 would still suffice for the casual gamer and probably for the more serious gamer on a budget from a performance/audio output aspect. It is hard to get excited about a SB X-FI when it cost $30 more than the motherboard in this market segment in our opinion. We think this is still an issue. Overall, the quality of the board is very good and the results speak for themselves.

    Pretty sure we'll get the "J" version in Europe, "J" versions are available on other Epox models over here. Also glad to see that the Epox board was not unduly handicapped by x8 lane PCI-E as opposed to x16 lane. All in all, even in the bog standard guise, it's a very good board for the money.

    Good review by the way!

    ^^^^^^^

    Those numbers are the initial value the memory will run if the HTT is 200. They all scale based on the HTT speed, so 1:1 = 200. All the other numbers are dividers that allow for running the memory at a ratio speed based on the HTT i.e. 133/200 = 4/6.
  • custommadename - Friday, March 17, 2006 - link

    The memory speeds in the review were Auto, 100 MHz, 133MHz, 160MHz, 200MHz, 218 MHz, 240MHz. Is there a 1:1 setting so that the ram speed increases with the FSB? It would be a shame not to have that seeing as how the ram can be overvoltaged to 3.2V

    Hey, this board looks great! The main drawbacks are the two silly component choices: no Gb ethernet and no HD sound (not like Nv boards have this anyway). Since my home network is 10/100 and I'm not an sound freak (and I have some 5.1 digital Live! cards to throw in if need be) those aren't drawbacks.

    I have a A8R-MVP that rectifies those problems at the cost of high vCore options.....pm me if you want to trade :P

    Its great having low cost Socket 939 boards, but where are the Socket 939 Semprons?

    Since Epox has had so many issues in the past with using poor capacitors (sorry I mistyped that, I mean crap capacitors) From GSC and TEAPO I think it deserves a mention that this board is using high quality Sanyo MV-WX capacitors for the VRM section and everything 1000uF and above on the board, and even not cheaping out on the lower value caps by using the top capacitor brand Rubycon for them...

    And if the editor can not distinguish from a good and bad capacitor brand please atleast post high resolution pictures of the capacitors so people looking for the info will find it without being as wierd as I am and recognize them by the style of their vents and type of colors used ;-)

    We did make mention on the front page and the features page about the high quality components used on the board. However, we did not specify the brand names or sizes utilized. We will do this in the future if the components selected warrants mention as it would assist the readers without your (not weird) ability to pick out the brand names. I did take a high resolution shot of the capacitors as I surprised by Epox utilizing these on a value board. I should have followed my instincts and posted the shot on the first or last page. Thanks for the comments. :)
