SATA is a connection type, it replaced parallel ATA connections. It's faster and runs cooler. You can probably do a google search on your particular computer and see if it is SATA-compatible. It most likely is, but I'm not a PC guy, so I derno. If you still can't find out, look up what a SATA plug looks like and see if the connector to your current DVD burner matches up.

Lightscribe is an HP product. You have to buy their colored discs and their CD/DVD drive--it then "prints" whatever you want on it in 1 color glory. It's essentially a fancy label printer that encourages you into buying HP products. Personally I think it's a waste of time because burning media is still a hit or miss at times and I don't want to waste more time than I need to labeling a disc.


*edit, damn you Picard for worm-tunneling your post before mine.
