IIRC Piru benchmarked cnet.device and got something about 800-900 kB/s (can not remember exact figures).
Not a particularly useful figure without knowing which CPU @ what speed.
Assume it is 060@50MHz and this probably is the top figure you'll ever get from an A1200 and that puts the maximum speed at 7Mbit/s.
I feel the figure will be lower with EC020@14MHz
PC Card 16-bit 255ns Byte mode = 3.92 MB/s
PC Card 16-bit 100ns Word mode = 20 MB/s
Amiga 1200, 14 MHz = 71 ns cycle.
Call me dumb, but what is the relevance of these stats?
