A BIG thanks to everyone who has helped me solved the issue of my crappy RAID 0 performance!
Thx for the tweaks...helped me!

np....while back I had an obsession with raid and went crazy with it...now it is water cooling...LOL....:woot: :toast: :clap: :banana:
10+ ms random acces time :confused:
I would just get a new HDD.
10+ ms random access time is slooooooooooooooooooow
unless raptors...about right...:toast: :woot:
Raptor performance seems rather weak for a 10k drive even if its a 1st gen, heres my drives in my sig compared.

the raptors have nearly half the burst speed.
This is what I get with 4x 150gb raptors on raid=0 (nforce)

EDIT--
HOLLY CRAP!
I applied the tweaks and look what I got:

WOW! That's big difference! Hope these settings are safe. Well...we see.
KK, let me get this straight, you have 4 Raptors In RAID 0, yet you only beat me by 2MB/ps

hows this for a single 74 raptor + areca controller? on msi nf4 sli x16..
64KB stripe/4KB cluster
i take it dat aint so good for a 74 raptor?
read all the replies but still confused on wats better? 16kb/16kb? 32kb/32kb? 64kb/64kb?
Wow thats some impressive numbers, cpu utilization is pretty high though. you spent $1000? on HDD's, now u should get an areca controller and watch those babies fly.
yah i know, just most people think 10k drive = fast which isnt always the case.Quote:

oh.. its just temporary.. ill be going for 2/4 raptors shortly..Quote:

BTW this is 4 x 36G Raptors 16k stripe default block, very nice improvement, thx guys
All this raid talk makes me want to get more HDD's and a good controller.:mad:
The more the merrier :DQuote:

I think only the 150 has NCQ

The "EASIEST" way to change your cluster size is to have a 3rd drive with Win XP on it....here is what you need to do.
1. Have 3rd drive with Win XP
2. Go to bios and change boot order to 3rd drive b4 Raid
3. Once in windows goto "Disk Management" (as soon as you click on it you will have a window pop up and ask you to select drive and it will also want to know if you want to convert drive to a dynamic disk...I always choose no)
4. You will see your raid drives as 1 BIG drive..now all you do is right click on the drive and click partion...primary partition...set size...now is where you can choose cluster size...you will have 3 boxes to check off...
5. NTFS or FAT32...Volume Label....Cluster Size......
6. After you check all of that off then you click off quick format and Voila...you have done it now do same on rest of drives....
7. once you have setup all your partitons and selected cluster sizes...shutdown PC unplug 3rd drive...change boot order so CD rom will be a bootable device b4 raid device and you are good to go on a clean install....remember once you get into the window when setting up XP you have choices to format drives again and choose where XP get sinstalled ...choose to leave as is...no need to format again cuz it will default to 4k cluster again.....
let me know how this goes for ....I have been doing this trick now for a VERY LONG time and I know for a fact that this is a fast and easy way...without using any 3rd party software.....
Hassan, looking at your graph there, you would GREATLY benefit from an Areca card... alot of untapped potential in those HDD's with the nvidia raid system. it seems to only be able to effectively handle 2HDD's.
hehe funny you say that Maxxx, I am on the lookout for one as my next upgrade, figure it would be ideal as I could move my array from rig to rig without worries. I sold my 3ware card a few months back and really miss hardware raid. i have a couple of new sata II 160G drives I wouldn't throwing into a nice array also... just 500 beans is alot
