In a previous post you asked for external burner recommendations, everyone who responded recommended LG. You actually linked to a full size LG (which is what is needed for any serious burning).
One of our mods likes her LG external drive (drives?) very well
Get the LG!
One more vote for the LG,
No one responded to your slim line Lite-on link, nor would any members here recommend a slim line over a full size burner.
I have seen no reviews of the Lite-on that actually included any media burning tests.
Also TY media should always be bought from member recommended, trustworthy retailers.
