The big question is, does he hope to keep the data stored on the array? My 
experience has been that unless you replace the controller with the same one, 
or one derived from it and known to be compatible, you will have to re-create 
the array, losing the data it held.

This is the main reason I moved to Linux software RAID, the array will run on 
any Linux system, no hardware incompatibilities.

The CPU overhead of even RAID is indignificant with today's CPUs, in fact it 
was so even a decade ago.

Sorry I can't suggest a card, pretty much any card should work if you con't 
care about the data, but if you do it will probably have to be a same or at 
least similar replacement card.
