Onboard raid vs pci raid

[ruibexiga]

Hello,

i want to make raid 1 but i don´t know wich is better: Onboard raid vs pci raid,
I heard that If you are using a PCI card RAID controller to mirror your files and your motherboard develops a fault, you can install the controller and hard disks in another PC and carry on working but If the RAID chip is integrated with your motherboard, however, you will need to find another identical board before you can access your data.

Is this true “identical board before you can access your data”? this means that if my asus p4c800 breaks i have to find another p4c800??

Do you know more pci raid advantages, besides this? What you think is the best?

All current IDE RAID is PCI. That includes onboard chips, such as onboard Promise controllers, which use a PCI interface directly on the motherboard. So there isn't a performance difference between that and a Promise RAID card. But it IS true that different boards can have problems rebuilding arrays from other boards.
