Bit-Tech put a SATA Plextor up against an established burner, a PATA 110D
from Pioneer.

We've found that the Plextor was slower in almost every test - it's one thing to be faster and more expensive, but it's rather another to be more expensive and slower. The one thing the Plextor has going for it is the SATA connection. This connection is undoubtedly more stylish and practical than IDE, but does it justify worse performance and a higher price? We don't think so, unfortunately for Plextor. The Pioneer has great performance, and an astounding price - we wouldn't recommed you look anywhere else.
