Onboard RAID vs RAID card

I've been thinking about this one for a while.

Could anyone tell me if it would be worthwhile moving from onboard RAID to a RAID controller card?

I'm only ever likely to use RAID 0, but if a seperate controller card would be faster or reduce CPU use then I thought it might be worthwhile?

Thanks for any replies :)
 
Hardware RAID controller is substantially faster than onboard in most cases. If they are just a cheapo one then the difference will be small but if you use a propper one with a hardware controller then the difference is huge.
 
For RAID0 there's no real benefit in using an add in card. Hardware add in cards are really only of benefit when dealing with parity based RAID levels.
 
Really depends upon what you are looking to use RAID for.

If just looking at RAID0 to improve disk access then not worth bothering with over standard built in.

Only really worth getting the addon cards if getting a proper card, ie 3Ware/Adaptec/Areca etc and then using things like RAID10/5/6 etc for resilience.

Certainly in a desktop machine then such cards are a waste.
 
Thanks a lot.

I'll stay with the onboard controller if theres not any real performance benefits.

Cheers.
 
Thread resurrection lol :p

What about when swapping components; does having onboard RAID (on mobo) mean you're either limited in your upgrade options, or you have to destroy the array? Versus hardware RAID where presumably you can just move the controller to the new mobo, plug the HDDs back in, and you're good to go, even if the controller has no battery backup?
 
battery backup is only for maintaining cache when the controller is performing cached writes during a power failure. to the other questions i'm not sure.
