Has anyone got more than about 5MB/sec out of a Mylex DAC960PD? I have two striped 7200RPM 68-pin wide ultra drives on a channel (each channel supposed to handle 40MB/sec) Having one drive on each channel made no difference. Running the following command resulted in 5MB/sec maximum throughput dd if=/dev/zero of=/u1/hog bs=1024 count=5000 I tried this of block sizes (bs parameter) of 1024, 2048, 4096, 8192, 16000, and 32000 Any ideas?
