M-DISC 25GB Blu-ray White Inket Printable Permanent Data Archival / Backup Blank Disc Media - 50 Pack

These discs work fine, but though there is an advertised 25GB capacity, you can't realistically get that unfortunately. I tried (and wasted) several recordings at and around 23-25GB and they all failed... I thought I had a bad drive or bad discs... then I noticed the actual capacity of a new and empty disc in explorer at 23.3GB. So I lowered my data to 21GB and it worked fine. Through several more recordings, I came to the realization that anything 22.5G and over FAILS, anything UNDER that works fine. That is the magic number and is consistent for me. So far have not had a failure if I keep the data 22.4G or under. At 22.5G and over, I get repeated failure. I haven't yet researched why this is, because there is only a single small file on each new disc that is miniscule, so not sure why I CAN'T get the full advertised 25GB, but that's my experience. I have an LG BE14NU40 burner. This brings the overall cost of saving my data HIGHER because I lose 2.5G of space on each one. Otherwise the discs work great.These inkjet writeable ones are best if you want to label... evidently writing on a regular disc could eventually leach ink on the reflective surface with time and render your disc corrupt.I use these for long term archives. I have dual HDDs for immediate backups, and copy that to MDisc every once in a while and store these offsite as an emergency backup in case of dual HD failure or the unthinkable, fire. This is for stuff I just absolutely don't want to lose, i.e. videos of the kids, pictures, etc... When technology changes, I can always move to it at any time.For now, this is best for my purpose. They work great. And longest lasting storage available at this time.If these fail for you at first, try keeping your recording to UNDER 22.5G!
