Um guys, a 48X CD burner only transfers data at 7.2 MB/sec which is well within the 33MB/sec that ATA-33 provides. We have a few 48X Lite-On's here at work attached via ATA-33 cables and have no trouble at all burning at full speed.
It's less about the data transfer rate and more about the fact IDE doesn't multitask well. In a master/slave configuration only one drive can be active on the bus at a time. Normally that's not a problem but when you do a CD to CD copy, sometimes the drives can trip over each other and cause it to take longer, or in extreme cases, coaster the CD. That's one reason why serial ATA is so nice, each drive is on its own channel (though MB makers need to start putting more than two ports on the board... )etilena wrote:If an 80pin IDE cable can transfer theoritically 66MB per sec at least, why is it a problem to hook a CD ROM and a CDRW together? Even at 48x you can only burn 7.2MB/s.. which is a lot, lot less than what the cable can transfer.
