Ah, these Ritek Archival seem to be super high quality BD-R discs but they are not M-Discs. This is why I am wondering if the M-discs are better or equal in terms of quality. The main reason for selecting Verbatim is the M-disc brand and it is easy to find places where they sell the disc. Other brands have become really hard to find, often it involves shipping, tax etc. from Ebay.

Also would this Ritek Archival be the best option for long-life archival DVD disc ? The reason is there are almost no DVD M-Discs left that I can find and I can not get it shipped here to where I am at. There are some Kodak Gold DVD-R out there but that is old stock, not something that is in production.

I did find that Verbatim did have DVD-R DL as Mdisc but not in production any more. Options for high quality archival media are slim now :-(

I found this about the Ritek Archival disc:

The Ritek BD-R DL 50GB 4X Archival Grade Disc is a high-quality Blu-ray disc certified by ADTC (Archival Disc Test Center) in Japan, bases on ISO/IEC 16963 standard. The standard specifies an accelerated aging test method for estimating the lifetime of the retrievability of information stored on recordable or rewritable optical disks.

ADTC concludes that estimated lifetime is up to 115 years.

With a maximum write speed of 4x, this disc is perfect for those looking for a reliable and scratch-resistant option for their storage needs.
