Comment on After 18 years, Blu-ray media production draws to a close — Sony shuts its last factory in Feb

Biggest one could take 2TB per disc

I mean it’s cool for a disc, but HDDs still beat that, Seagate just released a 36TB HDD to mass market, optical always lags behind on storage density and speed

From wiki: en.wikipedia.org/wiki/Archival_Disc

Sony used Archival Disc in their Optical Disc Archive professional archival product range, and aimed to create at least a 6-TB storage medium. As of 2020, they offered 5.5 TB Optical Disc Archive Cartridges.[14][15][16]

That limit I mentioned has nothing with the ‘technological limit’. Simply enough they lost with the adoption - if the clients wanted, they would get bigger archival discs.

  I’m aware, I’ve done heavy research for my own mass cold archival plans.
  
  It’s a physics problem is why it lags behind HDDs so much, and to reach that 6TB on optical it’s a cartridge with literal multiple discs inside. Adoption or no, it was never going to reach storage density parity with HDDs. Hell, even SSDs are having a difficult time taking on HDDs storage density

    Optical drives already are surpassing magnetic or even ssd. en.wikipedia.org/wiki/Holographic_data_storage it’s more advanced version of optical drives, for obvious reasons it’s just a prototype and most likely it will stay so for quite a long time but still, optical storage hasn’t reached the limit.
