# M-DISC

Hacker Approved page: https://hackerapproved.com/p/m-disc/

24 people recommended M-DISC in Hacker News comments, 6 had mixed feelings and 23 criticized it, November 2025 to October 2026. It was recommended in 6 of 12 months, in 14 threads. It does not meet the Hacker Approved badge rule.

**Verdict:** People recommend M-DISC as archival optical media that lasts longer than ordinary discs and reads in standard drives. Main caveat: expensive, and critics doubt current discs match older ones.

([source](https://news.ycombinator.com/item?id=47083948)) "Masked ROMs and M-Discs are those two things which can really last a very long time" ([source](https://news.ycombinator.com/item?id=49586071))

([source](https://news.ycombinator.com/item?id=46997976)) "M-disc is readable by a standard DVD-ROM/Blu-Ray drive." ([source](https://news.ycombinator.com/item?id=47000883)) "These are cool as they play back n regular players too." ([source](https://news.ycombinator.com/item?id=47012675))

## What people warn about

- Current discs may not match old ones (5 comments in the sample): "currently produced mdisks are not the same as older ones. Requirements for media has been relaxed a while ago" ([source](https://news.ycombinator.com/item?id=47067381)) "AFAIK there has never been good evidence that the BD-R M-DISCs have any special sauce" ([source](https://news.ycombinator.com/item?id=49586677)) "M-Disc Blu-Ray discs are made with regular Blu-Ray manufacturing technology" ([source](https://news.ycombinator.com/item?id=47017459))
- Expensive, especially for large archives (3 comments in the sample): "will probably cover most of the scenarios. It's still expensive, though." ([source](https://news.ycombinator.com/item?id=46736743)) "Because of the cost of M-discs, they stop making sense after 1-2 TB" ([source](https://news.ycombinator.com/item?id=47319596)) "I'm not sure m disc even makes cost-sense for smaller volumes." ([source](https://news.ycombinator.com/item?id=47020375))
- Niche format with little mainstream use (3 comments in the sample): "The problem with M-disc was that it was always a sideshow on the mainstream optical disc market" ([source](https://news.ycombinator.com/item?id=47021574)) "I’ve always been skeptical of niche archival formats, even ones as robust as this." ([source](https://news.ycombinator.com/item?id=47022980)) "The relative obscurity of the format, the drama around Verbatim's acquisition" ([source](https://news.ycombinator.com/item?id=49588445))
