onboard NF4 raid work as well as seperate PCI raid card

[kindest]

Having a debate with others about running a raid setup.
I'm under the belief that the newest NF4 mobos with built in raid
is a big selling point... in the way that built in raid is good..... or is still no comparsion to lets say a stand alone 3ware pci raid controller?

Also is it true using onboard raid that you can lose all your data if the mobo freaks out.

Was going to run a raid5 using onboard controller but now im scared.

RAID cards in "normal" PCI slots (32-bit 33 MHz) are limited to around 95 MB/s aggregated throughput. Chipset-integrated units do not have this limitation.

But yes, proper, non-toy RAID cards still are way ahead of the RAID units we see integrated into today's commodity chipsets. But they also require 64-bit, 100 or 133 MHz PCI-X slots to achieve the throughput they're capable of.
