Hm.. I get only 3.3 MB/s peak performance and perhaps 2 MB/s realistic performance on my 68060 with an IDE disk, would be interesting to see a few more datapoints. Iirc my IDE is on something like a 10 MHz bus. I remember a 68040 40 MHz had so little reserves im memory bandwidth and CPU power that even io buffered in RAM (not in disk buffer) had a maximum throughput of about 5.6 MB/s. Richard
