Hi Michael and thanks for your detailed answer and help (for once more)
I know this option. But I can't find such a card around. I also don't know if my friend's PC has a PCI express slot or PCI. I have to check that too. It seems to me a simpler solution to go for a PATA drive. Such a controller would double the cost as well. Nevertheless I could go that way if none of these drives is a capable burner.
I had already checked the LG review and both drives' results thread. It looks that LG is a very good reader and CD writer. If I interpret the scan results right, they are both decent DVD burners. But it is really difficult to figure out comparing different scans from different drives!
Thus, if I'm right that they both are equivalent DVD burners, I would go with the LG for the excellent CD writing quality. Please correct me if any of my assumptions are wrong.
My friend burns mainly CDs, DVD+R and rarely DL DVD+R. If one of these two is a solid performer in these cases I would go for it. And leave the SATA controller option for a later time
As far as I remember, the motherboard is Intel based chipset. Hopefully there will be no issues with the controller, even if LG is chosen.
Thanks again for your time and help!
