Hi, i have a striker 2 extreme with two hard disks utilising nvidia raid... I only managed 6800 in pc mark vantage and it lists my hard drive as the weak link.. Im looking at raid cards that can offer better performance than the on board controller but im confused with compatibility??? Does any one know what the best option out there would be for a pci x1 slot as the other two x16s are taken up with sli...
 
I have 4 velociraptors 300gb in a raid array.... when benchmarking, analysis reports that i am up to 70 percent slower than a scsi interface on the same board (striker 2 extreme)...
 
Yes ive seen that with vantage they are constantly providing links to new hardware...
I just wanted to get decent score in both 3d mark 06 and vantage (21000 and 6986) respectively... i will try out hd tune and post scores this evening although a raid stripe is probably going to be the best solution if theres no probs with the raid in the first place>
The comparison that they provided me with though online was embarrassing compared to the closest system match and for obvious reasons i dont want to miss out hence the question on sata controllers..

My cpu quad 9650 is ocd to 4.2ghz already and im happy there... i have quad sli also so is there anything else that can explain the low score in vantage??? Unless its just a marketing ploy?
 
Thanks, i see what you are saying... I just felt like i was too far behind in those comparisons and to be honest my pc performs fine > Was just trying to make sure that im not losing out in performance after the time and effort put into other things... Here are my hd tune results... if these are all ok then ill stick with the raid stripe (2 disk) that i have

Funny enough i just thought about the stripe size option... i think its set at 128... Also i will try without caching and see if performance increases..
I have 2 300gb velociraptors in raid stripe... Just trying to get the max performance out of the array but benchmarking continues to single the hdds as the weakest link in the system...
 
I thought that i lose half i my storage when using a stripe array and that would explain the title as a one disk quota... (half of two?)...
System has gone crazy with blue screens at the mo so once this is sorted i can test again... Hardware errors may just be the storage controller??
 
correct.... And if i had raid selected in bios for these drives then what probs could i expect??? bear in mind ive been pretty stable for the past month??
 
It would still be raid!!! I think i may have labelled these disks as "stripe" in the raid utility which has further confused me into believing i had configured a stripe... That should be sorted now just as long as the posted results above reflect its actual "mirror" status i can move on... thanks guys !
 
To throw a spanner in the works... ive just realised after opening everything up that i have the 150gb version of the velociraptor so the original array (stripe) was correctly configured!!!!! 150 + 150 = 300gb!!!! cant believe this. so somehow im only getting half the performance..
How do i get to the bottom of all this? the test above is valid so the question is What can significantly affect hard drive performance..
The array is labelled as healthy during post and it passed integrity checks im pretty sure, stripe size was 128, caching and extra performance boost features in vista were all turned on, drive has been regularly defragmented and is about half full.. I cant think of anything else!!
