Zorro 3 Bus Speed

[bbond007]

Wikipedia says it is 150 MB/sec, I assume theoretical.
What do you think?
Did any card ever use that close to that much bandwidth?

Although the Zorro III bus has a theoretical bandwidth of 150 MByte/s (32-bit x 37.5 MHz), the real transfer speed between the system and a Zorro III card is less than 20 MByte/s due to the limitations of the Buster chip. This is also the limiting factor with PCI expansion boards like e.g. Elbox Mediator PCI or the Matay Prometheus PCI (about 12 MByte/s PCI to 68k-system). DMA transfers between two Zorro III cards (or PCI cards on an PCI expansion board) can be much faster.
