Looking at new Plextor DVD+R/RW drives, I'm struck with the fact that the two drives they feature, one an ATAPI device, the other an SATA, differ respecting CD writing speed. The ATAPI writes at 48X while the SATA writes at 40X. The SATA device is $10 more expensive than the ATAPI. Can there be any reason for preferring the SATA? Its slower and more costly.
