setting up raptors in raid

[Krashnicki]

I have an Asus A8n-Sli deluxe mobo and two 74gig raptors I want to put in Raid 0.
I do realize that master slave jumpers are not needed for SATA Hard drives but do I need to change any other of the jumper Settings on my hard drives? For example one of the jumper settings is Spread Spectrum Clocking. What is this and should I leave it disabled?

Also if I attach two other 7200rpm sata drives in order to achieve raid0+1. Will this slow the raptors down

I would leave any jumpers on your raptors alone.

And to your second question; yes, the slower drives will kill the raptor's performance. You can only go as fast as the slowest drive in your array.

Hope that helps!

Unless your raid chipset documentation supports it leave it disabled.It will vary the clock cycle of the drive lowering electro magnetic interference,much like the one in the bios.If this is done on two drives that work in sync,you could imagine there could be problems.

for an a8n-sli deluxe mobo is it better to use the nvidia raid utility or the silicon image configuration utility to set up raid0. They both appear to be able to do the same thing. the only diffrence appears to be theat the silicon raid utility can also do raid 5. Has anyone had more success using one of these programs over the other?

just run the raptors in raid by themsleves... and if you have seond raid conroller setup the other disk and install windows on the slower ones and all programs on the raptor setup ....
