Onboard vs addon raid controler

[NialM]

Hi All,

I have a Gigabyte GA-7N400 Pro2 mobo that has the nForce2 Ultra400 chipset.

I have raid 0 using two 80 gig ATA100 drives running off the onboard GigaRAID IDE RAID Controller.

I also have (not installed) a Silicon Image Ultra DMA ATA133 IDE RAID PCI Controller Card (Sil0680ACL144 chip)

My questions are,
1) Are both considered software raid?
2) Would the performance be better from either one?

No, they are both done at the controller level. abd both offer the same perfromance plus 0+1 raid configs.

So...
1)NO
2)NO

Take into consideration that that your working with ATA100. If your still working in 32bits with a bus speed of 33mhz. Your performance is limited to the bus.

But, someone correct me if I'm wrong, but the controller card you have is a two channel card, meaning have two arrays. I think your GA-7N400 Pro 2 offers single channel raid. You may be happier moving onto the car and letting your cdroms share the open channels on the board rather than sharing.

I have the GA-8N SLI Royal mobo and I used the Promise SATA raid 0 configuration for my two 74Gb raptor. It's fast but don't know or haven't tried raid on controller.

Does anyone know if there is a site that compares raid chip sets?
