KennyR Edit: Actually, you could be right. But it's not just the transfer rate, it's the CPU load. PIO controllers like Amiga IDE or most of its SCSI solutions eat almost all CPU time at full transfer.
KennyR, I didn't mean to offend you.
DVDs use about 1.5MB/sec and thats final.
I just wanted to correct something that might have put the conversation way out. :-)
