Ok I've got a question about those raid scores, after enabling sata-2 with the feature tool, my atto scores went through the roof, why didn't it change my pit test scores for disc speed? Its still scoring between 145-160 for my 3 partions on that array. Is it just the way the pit tests, or is there something else?

I'm pretty sure that it's the way that the Pit tests. . . Just out of curiosity, what did you score before and what did you score now?

Revivalist-my pit test last night scored 159 on that same partion, and before then it was scoring about 150-152, and occasionally breaking 160. However that is my boot partion, and next time I reformat I'm going to change that up and keep the c partion blank and hopefully see if I can bump that up some.

Wow, that's really interesting. . . . On the pittest I score 240MB/s - 250MB/s (link)

 

Ok, now I'm REALLY curious about these results. . . . I think there's definitely a difference between 10,000 and 7,200 RPM that SATA II just can't make up for. It seems that this specific test in ATTO is just not revealing it. . . .

 

I suspect that this test is only testing the cache. If that's the case, it should show SATA II to have about twice the performance of SATA I. In fact, with four drives in RAID 0, SATA II should have a theroetical maximum speed of 4 x 300MB/s = 1200MB/s and SATA I should have a maximum of 4 x 150MB/s = 600MB/s. . . . If you look over this thread you'll see that the highest SATA I score in this thread is about 475MB/s and your SATA II score is around 875MB/s, which is almost twice as much. . . .

 

It's also interesting to note that 475MB/s for SATA I is 80% of theoretical max while 875MB/s for SATA II is 73% of theoretical max -- the law of diminishing returns.

 

However, your Pit score hits about 160M/s while Raptors will hit around 250M/s. That means that the Raptors are about 1.5 times faster, which is what we expect based on the difference in RPM. . . . So I think that the Pit is testing the speed of the spinning platter, not the cache. . . .

 

Based on all of this, I'm wondering if we can really say that SATA II is better for small files AND big files. It seems to me that it's only better for data that can fit in the cache. Otherwise RPM is more important. . .

 

By the way, X_C you might not want to use my scores in your study. I think that there's something wrong with my array right now. It's not matching up with other people who have similar arrays. In fact, HD Tach just gave me 37MB/s!!. . . I'll report back if I figure out the problem and get things up again.

asus has big problem with intel drivers and win xp, win 2000 nt file system 32k striped~~~ http://i40.photobucket.com/albums/e239/allen41547/raid.jpg ~~ anyone know of intel raid driver for p5wd2-e premium win xp, 975x chipset? win 2000 dont have jpg

16.0 = 11964-21236

32.0 = 213909-398721

64.0= 218628-416284

128.0 = 340262-520355

512 = 325582-518782

1024 = 406847-519831

 

 

first test w/sp4 needs tweaking :P

Looks good Allen, try testing your drives when they are not fully defragged, install a few programs on the drive your going to test and then run ATTO. The drivers I am using are from Asus website.

I'm not sure what kind of drives Allen is using, but I think this test does not show what SATA I Raptors can do. I think it's because the test is only transferring a 1MB file from the cache. So the only things that come into play are the interface speed (SATA I or SATA II) and the number of HDDs in the array. The RPM means nothing, and that basically rules out the main strength of SATA I Raptors. Edited by Revivalist

sorry guys im running 4-80 gig wd 8meg cache sata 150 on intel raid. Anyone using the asus p5wd2-e premium and want to use the marvell sata ports for regular hard drives go to asus site and select the p5wdg2-ws mobo and downloads, under drivers it has a new marvell 0.5.2 driver that actually works with the mobo for now at least. It will install and when you reboot it asks for drivers again but if you click cancel it still works. Cant get anything but hard drives to work on it so far, i got a sata dvd burner. Hard drives breaking in good, scores better between 5-10% fragmented ~~ http://home.insightbb.com/~allen337/wsb/ht...ID-1785039.html

Dont worry I_G it will let ya know right off if it will accept it or not, how long before rma? might mail you a copy

 

 

I slipstreamed a copy last night after reading your thread. ;)

 

Asus says 10 business days, after they get it. Should be back about November... :rofl2:
