The only way you can read the data on the disks is to re-establish the array on another board with the same controller type. RAID splits the information, literally byte per byte between the 2 disks, and unless you put them back into a functional RAID array, the information on them cannot be read, or assembled into anything that makes sense. Plugging them into a non-RAID controller and messing around with them will only increase the chances of corrupting the array or the information on the discs and could cause the array to become completely unreadable even if you do find another board with the same RAID controller. In other words if you hope to ever recover anything from the drives, leave them alone until you have the right controller available to put them back into a RAID 0 array. That is all you can do.
