DONT get Delta and DONT get creative. They both make POS cd rom drives, all deltas are POS and the 52x creative is a POS. The delta may be fast, but it sounds like a damn jet, the sound overpowered all the 17 case fans i had in my pc before. the creative sucks at reading cd-r's and such, and it has a habit of just dying. get Toshiba, they make the best drives, teac next and plextor if you wanna go scsi.
