The NCR/Symbios Differential Adaptec 2944 Differential Qlogic 1040 Differential have all been known to work, to a point. I'm biased against the NCR cards, but they're definitely the cost leaders. I use differential Qlogic cards all the time. I've also used the 2944 with some mixed results. All 3 of these brands use their own chipsets.
