Round 2 Speeding HDD vs. ICH9R
First off i am going to refer to ROG Speeding HDD as Speedy ( although from the tests slow poke might be a better name for it) Test Drives are 150GB WD Raptors
First up here we have the linear read from everest on the Speedy controller. As we can see it came up with a disappointing 96MB/s for a maximum. To save time i just did the first part of the drive. I wanted to focus more on the File system benchmarks which are coming up in a bit. I believe these will show a more real world result since i would say most of us have are drives formatted to the NTFS file system.

Now we have the Intel ICH9R Raid 0 with a stripe size of 32KB. From playing around with stripe sizes the 32KB yielded the best performance on my hard drives. As we can see from the test results a 175MB/s maximum linear write Puts a serious whooping on the speedy. Very close to a 100% gain!!!!

But these tests are raw writes Lets see how the Two controllers Fair in a more real world test With Si soft Sandra's File System Benchmark. A quick note you can perform this test without destroying data So anyone can do it and you don't need your OS on a separate drive. First Up we have the Speedy results.This shows a Drive index of 102MB/s . This test combines read, write and latency to come up with the score.

So not Quite the Romping it gave the Speedy in the linear write tests But If my math is correct which it very well Might not be, I have the Intel Up by Just shy of 20% over the speedy

now lets look at the linear Write tests of One Single WD 150GB raptor on the two different controllers. We have speedy first
Now we have One raptor on the Intel

Notice i have a couple bad spots in one of my drives. Teach me not to buy OEM ever again. But these test are about the same. Not much of a difference . Not for sure but i believe that the Speedy ports are some how combined into one channel. But this is just a theory , cant find any tech specs on it.
So sitting there with my two drives non raided on the Intel controller I decided to get crazy and converted them to dynamic disks in windows disk management then i proceeded to make a software raid stripe. I have read quite a few forum posts where people say that Windows software raid is not good that hardware raid is a lot faster. So lets take a look at the windows software raid 0 results. Wait can this be the software Raid 0 shows a 127.95MB/s index beating the Intel ICH9R hardware raid that had a drive index of 127.42MB/s. Wow a 0.5 MB/s victory for the Windows software Raid 0. To bad you cannot install windows on it. Just to be sure i ran that test 3 times came out the same. ( Note there was no way to do any other tests on the software raid because all the benchmark programs saw the raid as two separate drives. So File system was the only choice i had )[/LEFT]

Now this next test i didn't think would be possible i turned the speedy to normal mode with both drives in the speedy ports. The Rampage extreme manual says this normal mode only supports one drive. Well windows saw both drives installed the drivers. So I converted to dynamic disks slapped a software raid 0 on them and ran the file system benchmark. Once again software Raid O with a win. With a drive index of 111MB/s beating out the Speedy controller by 9MB/s . But still slower then the Intel ICH9R tests

From my first findings i said that windows booted up quicker with just the speedy enabled which it did. So i decided to give the Intel the same opportunity and hooked my external dvd Esata drive up via USB. Disabled Marvell completely and my windows boot up time is even quicker then it was on the speedy controller. So either way you look at it if windows has to load both the Marvell and ICH9R drivers it will just take quite a bit longer. Anyways i know i had more to say about this but i have this crazy mod i am dieing to work on today ..So I'm Off till next time
