Single HD Image copied to new RAID

NachT · 14 Jul 2006 at 19:11

Hi, I upgraded to RAID 0 recently.

I took an image of my single drive, formated it and built the RAID with my new drive, then put the image back on across the 2 striped drives.

Should i have freshly installed windows onto the striped pair, or would the way i did it make no differance in performance?

I can't see any differance in performance using applications and games that were originally on my single HD, that i copied over in an image, but i do see improvements on freshly installed apps that i installed after i got my RAID setup, also drive speed programs say there is an improvement.

Is it just me that thinks my OS and originally installed games arnt running as fast, or would what i did effect the performance, rather than freshly installing the OS ?

Any one have an idea?

There seems to be no performance improvement in the way i did it. I'd like to be 100% sure that what i have done would effect it, and in what ways before i do a fresh install. I'd hate to have to re-configure my OS and install / re-configure all my apps to find out later that the way i did it in the first place was ok hehe.

Could any one els back this up

Thanks guys,

Your test shows way better results than mine heh. What stripe size do you have?

Heres my results, 2x 150 Raptors on SATA 2 ( They don't work on the SATA ports, so i guess they're SATA 2 )

Thanks for the speedy replays guys. Yeah my raptors are extreamly slow, I think it's because of how i've put the image back onto them as i said above. It might be best for me to do a fresh install the right way onto them.

My controller is the Sil 3132, my storage 7,200 disk gets a better result than the 2 raptors heh >.<

There is something wrong, my Hitachi Deskstar 250Gb drives get ~110Mb/sec average in HDTach and I did the same as you.

I cloned my single IDE drive to my RAID0 using Acronis TrueImage and it should not matter at all

I used Acronis TrueImage too, but mine didn't work by the looks of things lol.

I guess i'll just do a fresh install when i have time, i'll have to put the drivers for my RAID controller onto the XP disc because my floppy drive broke *sigh* ^_^

It's just one of those days...

isn't it more likely that its something to do with your raid drivers rather than the image?

Maybe, because instead of saying Sil 3132 blah.. what it usually says, it just says "Disk Drive"

Last time i tryed to update the drivers it wouldn't let me though.

Yep, it wont let me update the driver, i'll just format. Should be able to use my enhanced north bridge on this fresh install, if i remember right you can use enhanced north bridges on a RAID right? :rolleyes:

Took me a lot of hours, but i know what the problem is now.

My SATA 2 Controller is crap. It's the Sil 3132.

With 2x 150 GB Raptors on RAID0 on the Sil 3132 Controller I get a MAX read of 80 MB/s

1x Raptor on the Sil3132 Controller gets me a max read of 69 MB/s

So i broke the RAID and stuck one of the raptors on the SATA controller (Sil 3112 I think ) and the single raptor alone got a max read of 114 MB/s without any enhancing in the bios.

When i get this all fixed i'll post some results.
