[QUOTE=Albert;2753976]The first internal Asus (B5) should be a LiteOn. The second (D3) might be an LG. The LG DVDRW drives have a weird range of speed choices, and bit setting cannot be toggled (though I think that means it’s always enabled, which is generally good).[/QUOTE]
I know I already tried LG the newest drive and it doesn’t bitset/booktype so they lost my business for upgrade drives…
[QUOTE=Albert;2753976]When it comes to overall quality of writes on good media, they should be similar, but I would give the nod to the B5 when it comes to using everyday media (LiteOn drives tend to handle everyday media a bit better).[/QUOTE]
My old trusty BD Liteon burner 212 still works and does booktype/bitsetting automatically which I like.
[QUOTE=Albert;2753976]As for the external drives available to you, the few results I have seen from the Asus have been okay. The Samsung’s results have been fine, too, but Samsung’s slim drives have randomly had weird problems with some media as of late, so I would give the edge to the Asus. I’m not sure who is the OEM behind the Asus drive (I would guess LG, but I can’t be sure).[/QUOTE]
I avoid external this being my experience with a LS BPNS40 drive seems to fail consistently when trying to write BD media.
