OK, so it's already known that the Philips SPD2413BD is a rebadged Lite-On LH-20A1P. I know, because I owned one myself.
Now, Philips has two other Lite-On based IDE models, the Philips SPD2414BD and the SPD2415BD. Both are 20x drives.
Any guesses as to what they are rebadges of? Could one be a 20A3 rebadge and the other a 20A4 rebadge?
Or maybe I'm wrong and one isn't a Lite-On rebadge at all. Anyone know for sure?
