SCSI = fast and reliable
IDE (before UDMA I guess) = slower and unreliable
CD burner needs constant data flow, as can't stop/start/reposition mid burn.
First CD-R drives were thus SCSI
When they made IDE CD-R, they thought...
"Shall we write a whole load of new commands/drivers, or shall we emulate SCSI over the IDE bus".
And so SCSI emulation happened
Windoze apparently also uses SCSI emulation, you just don't know about it.
Newer drives have big cache, but still use SCSI.
Hope that helps.
