(solved)raid performance

Recommended Posts

Ok I went with what I thought was going to be an upgrade going from the Asus M3N78 Pro to an Gigabyte GA-990FXA-UD3 and my raid performance took a big hit. I noticed it in PC Mark the first time I ran it. I lost close to 800 points even tho most of the test showed better results till I reached the hard disk part of the suite. Anyone have any idea what I can do or maybe give me some suggestion on ways to get some of the drive performance back? Im using the on-board SB950 chip for raid

 

 

 

 

rebuilt my raid from scratch and changed one of the write settings and its working back up to par :-)

Do you have the RAM cache enabled for your RAID array? You have to install AMD RaidXpert or whatever it's called to set up the RAID controller properly.

I have raidexpert installed and where would I enable ram cache?

You have to connect to the server (which should be a link on your start menu). I'm not entirely sure where it is in the options, but it's somewhere in there. :lol:

The only option I have that refers to cache is write cache and its enabled as well as NCQ

i left it at default of 16kb I think, here is a score comparison IDK what else to try

16 KB is waaaaay too small for a RAID array of HDDs. Use 128 KB.

Does that means I'll have to start from scratch? Meaning re-install windows and everything?

You can do system image backup with Windows 7 to another drive or a network location then just image it back. That's what I do when I need to change something like that.

ok cool I'm making a back up now, so 128kb is going to be best?
