Could anyone tell me which of these two drives would be a better buy? The 716 seems to have a lot more features, like PoweRec, VariRec, Intelligent Tilt, GigaRec and AutoStrategy, and has 8Mb buffer compared to 2Mb for the 740. However, the 740 is faster at writing for several media (except DVD-R DL) and has a different (better?) chipset than the traditional Plextor drives. On the other hand, the 716 seems to be able to read at various speeds whereas the 740 appears not to be able to. The 716 also has disk quality verification capabilities. Are all these features that seem to have been dropped from the 740 important?
