Sony develops a cassette tape with 185TB storage space

No, Sony isn’t feeling nostalgic for still creating a cassette tape. Although this device is considered a thing of the past, it carries a whopping 185 terabytes (or 189,440GB) of space for storage purposes alone – bigger than any modern CD, DVD, or Blu-ray discs that you can see today.

The reason that the Japanese company made a cassette tape with this much capacity isn’t for making a mixtape that would last decades to play. No, it’s mainly for archival purposes since magnetic tape storage are high density tapes that are cheaper, more power efficient, and more reliable than storage that are disc-based.


This cassette is equipped with 148GB of writable space per square inch. Comparing it with the normal cassettes used for storage today which only has 29.5GB per square inch, it is definitely a far cry from Sony’s latest innovation.

The company mentions that it would like to extend this technology to the public, but it’s still undisclosed when or if it will really push through. This brings us to a question: Does an ordinary consumer (like you, for example) need 185TB of storage?

    it depends, how much porn does a man really need?

    I am pretty sure that the consumer version of this product will not be offered with a 185 TB capacity.

    working in a creatives company dealing with large files.. i need this!

  4. someone says:

    I probably would have filled 10TB of that tape by now if it came out 4 years ago.

  5. dude like Wo says:

    im sure that most of the people this day wants a device with an almost unlimited storage capacity, tho the problem here is how to process, if that thing process few Gbs of data for several hours, then it is a no.

    if you can handle the sequential read access times then why not.

    • witchcraft says:

      Sequential would theoretically be fine. It’s random access times that are gonna be piss-poor. If ever they make the drive motors spin faster to make up for it, then they might also tear the tape to pieces.

    very good for archiving old database files.

  8. Hen-Sheen says:

    I’m no stranger to this tech. In fact, this would be ideal if I have a Commodore 64 in my possession. And if that tape was Laserbeak, I would stop whatever I’m doing, and runaway like there’s no tomorrow!

    Does it mean it needs to be rewinded as well?

  10. Mr A says:

    By public I hope it doesn’t mean enterprise public. It wouldn’t hurt for the average consumer to have an archival option such as this.

    Yes person like me having number or project definitely needs it. I already have 16 external drives @ 1TB each contains Structural Plans, ACAD layout and other paper documents usually DPHW required. I have my own 3TB WD Cloud for fast, easy and convenient use without paying such amount to Smart network. With 3TB WD Cloud I can sync all my devices from work to home.

    Looks like a lot of people here don’t know that this tape storage isn’t ideal for daily use. Tape storage is commonly used for archiving data and not as a storage device that can be used for daily activities.

    A lot of data companies still use tape storage because they’re much cheaper and more reliable for archival and long-term storage than your typical clacking mechanical hard drive.

      True that, we’re using PowerVault Tape Drive Storage, it’s not meant for Consumer-oriented data backup and archiving…
