[How to] install Leopard on a software RAID
 

I've juste updated the wiki with this howto.

The XBench score is not very good for a RAID but take a look at the sequential test.

Report success or failure here.

Any chance you could find/add a nforce4 raid driver in the next rev? For the onboard on the sata raid.
Most hw raid computers are nearly twice as fast as without raid.
I think Leopard install on raid would be very fast.

Does the above indicate that with software raid on one harddrive the hd is faster?
you need to show the baseline for comparison

Errrm, YA! Disk speed on Hackintoshes usually sucks by comparison! Get xbench - the baseline figures are there and they're all "100". A 289.25 is almost 3 times as fast as the baseline Mac Pro... Check the "xbench scores" thread to see what others are getting with "regular" internal HD's. Zephy's score is fairly amazing.

Zeph what mobo are you using is it nforce4?

I'm using an A8N5X NForce 4 mobo.

In that case you are scoring nearly double what I do for a single drive. Which I reckon is good going for any raid setup.
As soon as you come up with a way to do it without a working installation, I know I'll be giving it a go.

Here is my XBench without the software RAID.

That's why I say that the score is low for a RAID.

I wonder why my disk scores are so low compared to yours, the uncached write seems to be the biggest factor I get just over 1MB per sec.
I wonder if disc size is a big factor. I'm using an 80gig Seagate disc.

What's your SATA chipset ?

Nforce 4 ultra
