Debian BDXL distribution

Why ever would you want to download the entire distribution? No internet connection on the target computer?
I bought some off brand BD-R DLs and they all (four of the same) failed burning, even at the slowest speed and after cleaning the lens. A similar thing happened to me with another brand of CDs quite a while back with a DVD burner, and I had only used first tier since then.
Verbatim just worked and at the highest speed.
An interesting product:

If penta layer BDXL is developed, it should be "160GB", so that it can back up such common drives.
Hexa layer seems kind of ready at 200GB.
A 320GB deca layer BDXL was also developed, so it would fit with that line of reasoning.

So.. How common are such drives in PCs? Perhaps I’m colored by my Mac + server background, but I haven’t used anything but USB and (at most DVD-sized) ISO images to install an OS for many years...
The 6 and 10 layer prototypes or almost products were developed a long time ago but not brought to market yet.
What came to the production/enterprise markets are the cartridges with 150GB per side optical discs.
The only quad layer 128GB discs I've seen come in a cartridge.
100GB M-DISC only came out in 2016 (so my drive theoretically only supports single layer).
It seems optical costs 50% as much as other solutions for cold/nearline enterprise storage.
The price of BDXL discs only came way down near the current level around 2016.

Single layer BD-Rs and CD-Rs of the same brand work at the highest speed.
Single layer BD-REs of another off brand also work at their highest speed.
Well, I checked the manufacturers:
Worked:
CD-R (brand1): "Plasmon Data Systems"
BD-R (brand1): Moser Baer
BD-R DL (Verbatim): "Verbatim" (Taiwan)
BD-RE (brand2): Ritek
Failed:
BD-R DL (brand1): CMC Magnetics (Taiyo Yuden optical disc successor!!)
Is my drive bad?
Now, one thing is to burn without errors, another not to rot quickly.
It seems other people have some problems with this drive and there are no firmware updates.
From the moment I opened the box I did not like it because of the cheap plastic.
Never again this product line.
Wait, I bought the CMC discs before they started producing some TY tech products, so maybe the drive is not really bad.

But a bad thing about my drive is that it is not possible to measure disc quality.
I should make a couple of clarifications, to avoid confusion:
- Plasmon Data Systems is an equipment brand. Many different manufacturers with varying processes use this code.
- Verbatim quite often outsources disc manufacturing to different producers with no issues.
I just burned a Verbatim DVD+R successfully again. Manufacture for my version seems to have been outsourced to CMC Magnetics in Taiwan.
I also have some TDK DVD+R which worked well which are just Moser Baer. There are some Philips with the same code. I burned one a couple years ago and I got zero errors now in a media scan.
Many years ago I bought some Philips DVDs and I think they all failed to burn.
