You were not really specific about why the server took a ****. If you lost a hard drive, then you’re fucked. If the system board crapped out, you should be able to plug the drives into a different motherboard that supports RAID 0 and recover the data.
RAID 0 should only be used in cases where extreme drive speed is needed (especially write speed) and the data is either expendable or backed-up religiously. RAID 0 offers you NO data protection whatsoever. In fact you don’t even have to lose a drive, if you lose a SECTOR you are fucked because of the way the data is striped across multiple drives.
