I have a laptop with a DVD-RW drive, and I noticed that many laptops have pretty similar optical drives in them. I know that not all laptops are the same and many have custom components, but is there a standard type of optical drive that some of them use?

I would love to upgrade it to a Blu-Ray burner if I could.

My laptop is a Lenovo IdeaPad G780 (59352497), and the DVD-RW drive that I took out of it has the model Philips & Lite-On DS-8A8SH20C.

This is what the port and drive look like:

Visually, most of the laptop optical drives I see appear to be similar, though looks can be deceiving, I wanted to know if these are some standard design or not.

I also noticed that little tab (noticeable in the last two photos) that seems to be designed to allow the drive to screw into my laptop's chassis. Is this standard too, or was this some custom addition added to my laptop specifically? Would this tab be something I could de-attach and screw onto the new drive? I saw what looked like screw holes in the same areas on some of the drives I looked at.

And finally, the drive has some custom plastic attached to the front so it pretty much matches up with the rest of my laptop's design/casing on the edge. Is this also some standard in that I can detach it and re-attach it to the new drive? I couldn't figure out how to take it off.

So finally.... if this would work and I can upgrade the drive, any recommendations? There aren't a lot of options out there, especially if I want a Blu-Ray burner. These two were ones that seemed ot come up often:

(Hmm, prices seem to have gone up, that first one was about $35 a few days ago)

Are these any good? The second one seems to just be a newer model of the first one, but I am not sure the extra features warrant the higher price. I tried to google it, but couldn't find much solid information on what this M-Disk support is other than something that somehow increases longevity? Seems the biggest advantage is that the newer model supports BDXL... though it mentions 100gb triple layer, I thought BDXL could go up to 128gb quad-layer?

Any advice on all this?
