Digital 4X 128GB BDXL Quad Layer BD-R XL White Inkjet Printable Blu-ray Recordable 50 Year archival Discs - 3 Discs

Great back up! Burn time is pretty long (around 3 hours) on a LG DVD M Disk burner. I used the burn software included with the LG burner. The actual practical storage capacity is less than 128GB (around 112 GB for my system.). Yes, It is possible to add files to the disk as long there is capacity and if the disk burn is NOT finalized. These archival disks are way better than memory cards (SD, etc), USB memory sticks and solid state drives and regular hard drives.

Bought a 3 pack of these Sony BDXl discs to see if they would work in my new burner rated for up to quad layer 128gb capability. Burned first one using latest Burnaware program and it failed. Went through burn and check just fine, no errors and no rereading noise like I saw with 100gb verbatim mdiscs but when I tried to copy off the files to a test directory on computer using the same drive and computer it failed it failed to read files in to the 2nd layer, just like happened with the Verbatim 100gb m discs (I got 1 out of 10 of those verbatim discs to work). Seems like the 2-3-4 layer blue ray multi layer technology is non-functional. I tried with 2 computers, 4 blue ray burners, and many discs wasted now from 2 different brands. I tried 2 different programs as well. Only single layer 25gb discs seem to be reliable enough to use. I am wondering how is this possible in 2024?? anyone have any ideas?

These disks are not labeled in any way as M-DISKS or as a Sony product, they use similar phrases and wording such as "50 Year Archival Grade" and "Weather Resistant" that may confuse the buyer into believing that these are actually M-Disks.Even I had to look really closely at the characteristics and labeling to make a decision on these disks.Also, found somewhat conflicting information in the reviews, such as one user writing:"The Sony QUAD layer blue ray disk works great." but it doesn't state anywhere that these are Sony disks, and the same review also says: "Unlike M-Disc- there is no recommendation by Sony to store the Sony disc in an individual jewel case." And again, I see nothing indicating that these are Sony Branded Disks, (Maybe they were marketed at some point like that, but the website has been updated, I'm not sure.) But it seems like something is not lining up.Beyond that, I just want to say that I cannot give any feedback positive or negative about this product. I simply wanted to bring the potential buyers attention to the fact that these are not M-DISK and that is what I personally was looking for when i stumbled upon these disks.

Buyers beware! I was going to make a youtube video about putting steam games on a disk, but the backup is gigabytes large. The disks that are being advertised are only 119 gigabytes large. The number that is on the packaging states "128 gigabytes", does not state anywhere that this number is referring to a decimal based byte (1000 bytes per byte), instead of the widely used binary (1024 bits per byte) that everyone, such as cell phone, and hard drive, sd card, and flash drive manufactures use everywhere else.
