There's nothing wrong with asking questions.

The Verbatim 43888 has been coming with a BU40N in it lately. It can be flashed as the Flashing Guide explains to support LibreDrive. The last link in my last post is a link to Billycar11's ordered list drives, best to worst. There are a couple of other mobile LG drives on that same line as the BU40N. Which ever you can find that's the cheapest and comes with a decent return policy.
The mobile drives are almost always powered via a USB port(s). They need to be plugged into high powered ports to operate well. If necessary, you might have to get a high powered USB hub to power the drive. The mobile drives don't work well when they don't have enough power.
The other thing to bear in mind as you start down this path is you'll likely end up with more than one optical drive. Personally, I've got 4 (and a 5th one, yet unused sitting on my desk). In my experience, some drives just don't like some discs. When I only had one drive, when I encountered a disc that wouldn't work, I'd clean the disc, sometimes several times, and maybe I'd be able to make it work, maybe not. After I got the second drive, while my success rate didn't go up to 100%, it did definitely improve. When a disc wouldn't work in my main drive, often (though, not always) the disc would work in my other drive. Eventually Pioneer drives came to be supported and my two Pioneer drives are my main workhorse drives these days. Occasionally I come across a disc that even with my 4 drives I just can't read. When this happens, I replace the disc and almost always the new disc works fine.
Generally speaking, the hardest discs to read are triple layer 4K UHDs. These will hold up to 100GB of data. On MakeMKV's first screen, after you put in a disc and MakeMKV reads it, on the bottom on the right side of the screen MakeMKV will tell you details about the disc, including how many layers it is and how much data is on it.

You probably have a couple of these discs already in your collection. After your new drive is properly flashed, try to rip a couple of triple layer discs. If you succeed, the drive is probably good to go.
