Is the LSI series of HBAs really the only = choice outside of onboard controllers? It seems like they are troublesome, = support is spotty, and this whole flashing process gives me nightmares. Also personally, with the few boards I=92ve seen with built-in LSI = adapters have always been a little wonky compared to their non-LSI counterparts. Is this all just the end-result of LSI basically buying up everyone?
