29160 is 160Mb/s, the 2x ASB 3940U2W might be dual-bus 40Mb/s or 80Mb/s; the 2x AHA-2930CU are 8-bit Fast SCSI (20 Mb/s)

Are you saying the 2930CU will be faster? It appeared by looks alone to be older/slower. But that is with my limited experience.

I was just saying that they are good quality cards and that their slower speed could be a good point in old systems.. as these cards will never overload the PCI bus.

With the 2930cu, your HDDs will run as fast as with the Wide cards, except for big-files transfers between drives.
