Sony has a track record for switching chipsets as they move along from model to model. The DRU-540A used the same Sanyo chipset that is used in the PX-712A. Upon entering the 16x game, Sony switched to MediaTek as its supplier for the servo controller and analog signal processor for the DRU-710A/720A units. Now, Sony has changed their chipset to that used in BenQ’s DW1640 as well as Plextor’s PX-740A.

This may turn out to be a good thing, since the DW1640 and PX-740A drives performed very well in all areas. But we all know that the performance of a drive depends on not only its hardware, but also its firmware. The DRU-810A comes with the 1.0a firmware, which is also the latest and the one that we used in our testing.
