Let's say I've got a RAID0 system (two drives mirrored) plugged into a motherboard's built-in Promise RAID controller.

Let's say the mobo blows a gasket, letting out the expensive Blue Smoke, and won't POST any more.

Now I buy a new mobo, and it's got a different brand of RAID controller, or perhaps none at all and I'm forced to purchase a third-party RAID card which may or may not be a Promise card.

If I plug those drives into the new system, will they work and will their data still be intact? Or is the RAID formatting and information a proprietary standard that varies from controller to controller?

(I'm aware that there's other issues such as the OS having all the wrong mobo drivers installed. Let's assume all I want to do is recover the user-made data before wiping the drives for a new OS.)
