MDisc is more durable? Or just marketing?
 

mdisc is superior in durable e resistance of dvdr verbatim and ty? or marketing? i buy mdisc amazon? mdisc degrade in light, heat and humidity?

It is not, no.
Verbatim and Taiyo Yuden are both better media.
M-Disc is expensive AND not as good. So it's double punishment.

I see mdisc manufactured by Verbatim
mdisc uses dye inorganic durable and sturdy?

M-Disc is really more a technology than a brand. It's complicated, because it's unique.
But it's mostly just marketing.

Verbatim likes to do anything is can to maximize profit:
- gold plated DVDs (because gold discs suck)
- cheap versions using CMC/Ritek
- M-Disc
- quality MCC

I can't say I blame them. Sometimes the market demands crap. They provide it to those that insist. A sucker and his money are soon parted.

his opinion I should buy verbatim dvd-r azo or mdisc? I look for durability and resistance of the DVD disc to keep my files for many years decades
I've read on the internet in 100 years of useful life of dvd-r verbatim azo, this is a lie?

Buy both.
Burn everything twice -- once to each. Then compare them for yourself.

2x archive is good backup policy, after all. ;)

I do not know mdisc people speak but he has dye inorganic, high price and 1000 years to save files

dvd-r verbatim azo Mitsubishi I do not know the life expectancy useful it but people speak in 100 years expectancy

What is the best?

I'm not doing this with you again.
You can either trust our independent media testing, or you can trust the company selling the product.
We say MCC.
I don't care what they say.
Walmart claims to be the best at everything, and most people know they suck at most things.

Verbatim dvd-r azo mcc has a higher resistance to heat and humidity compared to other cheap Medias CMC, Ritek etc.?

temperature and humidity affect which parts of the DVD-R disc?

Verbatim even "makes" compatible burners https://www.nierle.com/en/article/32....0,_Black.html

MiniDisc is not meant for archiving, It was a distribution format for music listening and it is 5 times compressed compared to CD, I don't know what is your archiving needs but if it is music? I would go for multiple formats, first save a backup on a hard drive in WAV or FLAC, Make a second backup on a SD card they are big and cheap now up to 128GB, make a third backup on a tape format such as DAT, I would stay away from any optical medium for archiving.

By 'M-disc' the OP means the millennial disc, not MiniDisc. I don't think DATs are even sold anymore, and they are a magnetized format.

If I recall, the studies on the M-disc have only been for the DVD version, not for their blu-ray offerings. I once asked if they had any evidence showing the longevity of their blu-ray version but they couldn't give any.

The M-discs were tested here?

I am thinking of buying Verbatim MDISC, this disc is reliable, sturdy and safe? The construction of this disc allows you to have a disk for many decades and keep the files 100% good?
