[QUOTE=pcarey;2631469]Bought the Asus DRW-24B1ST months ago. Tried it. Mediocre performance. Cross-flashed it to a Lite-On. Still mediocre. Also bought an Asus DRW-24B3LT, an OptiArc AD-7260S and probably a couple of others. All Lite-On clones. The AD-7260S was probably the best of the bunch, but still nowhere near as good as my AD-7200S or Pioneer DVR-215D.
Funny, but the Asus DRW-24B1ST was the second one I had. The first one had so much noise and vibration I couldn’t use it, so I returned it to NewEgg for exchange. But it wrote excellent discs, so I was encouraged! Anyone can make a bad drive once in a while, right? The replacement was smooth and quiet, but couldn’t write a decent disc to save it’s life! Getting a decent drive seems to be a real crap shoot anymore - at least for me.[/QUOTE]
The AD-7240/7260 Sony Optiarcs are not LiteOn clones, and I found both to be rather good burners for decent quality media. They are based on a NEC chipset, unlike true LiteOn drives which are based on Mediatek chipsets (the exception from the rule were the LiteOn iHASx24 Y drives which were in fact AD-7240 NEC rebadges, not true Mediatek LiteOns like all the other iHASx24 A/B/C drives).
The DVR-217 is the last true Pioneer drive, and if you are lucky enough to find one, I’d say you’d better grab it fast before someone else does It is a good drive. Check out the relevant thread: http://club.myce.com/f87/results-discussion-pioneer-dvr-217-d-f-vxl-s17-s17j-265795/
The later DVR-218 and DVR-219 Pioneer drives are QSI clones with little to no third party support, and I would say not as good as the good old Pioneers.
