Yeah, it is almost like FAQ I know.
When it comes to DVD-R and CD-R I assume that buying good quality media is enough to be confident that the disc will last a minimum of 10 years or more when stored in a optimal way. And even after that you would expect that there might be some CRC errors and so on, but you would still be able to read the whole disc. Also these discs have been around for a long time, proven technology and it works.
I recall my older discs I did read back, I had no problems with any CD-R, be it cheap silver, or expensive gold, worked just fine. The issues I had was with a few verbatim discs, but again it was only CRC errors that prevented some larger .avi where damaged. If I had regular information like photos documents and so on, it would only have been a few files damage. All the discs and the other files on them I could read back.
I am aware of that M-Disc thing, but how proven is that, and you need specific hardware to read that. I am looking for reliability and stability of media for archiving. Should I then stay away from BluRay and M-Disc and stick to DVD-R as I assume they are just as safe as CD-R. I will still maintain my archive and have the files stored on offline hard drive that I will eventually replace in case of failure, I doubt my personal pictures, videos etc will exceed 500Gb in the near future so nothing to worry about on that front.
The problem I have with BD-R is how reliable they are, lots of information in the forums and problems people have had or have. It is also hard to get hold of media compared to DVD-R or CD-R and issues with quality of media and hardware problems. And also the problem that when BluRay came around the interest in burning optical media has dropped like a stone, there are few people now that I know of that even have a burner unit. Most (morons) stor it in the cloud etc, but sure, if you have pictures and stuff that you do not care about, I guess that works.
The only real drawback with DVD-R is storing video, consumes a lot of discs, but I have aluminium boxes and so on from before, so that problems I can work with.
What do you think is the best option for me, you know much more about optical discs and hardware.
BTW, thanks for talking time to post a reply, this forum is not as active as it once was. Kind of sad as optical media is the most safe way to stor information for archiving.
