Massive Increase in Hard Drive Storage in 3-5 years

IBM 3380 - First 1 Gig Hard Drive, 1980

I never delete emails.  I know people who spend lots of time going through every email, dealing with it, then deleting it when they are finished.  I don’t. The amount of disk space required to store thousands of emails is so trivial these days I stopped deleting years ago.  This new technology from Seagate and others will increase drive sizes by a factor of 50 in just a few years!

From the article:
“Imagine the storage capabilities of a 100 TB drive. 250,000,000 average MP3 songs or 250,000,000 12 MP photographs. Or 2000 completely filled Blu-ray discs or hundreds of 3D movies.

So what can you do with a 100 TB drive?  Well, how about keeping a local copy of every single thing you ever see on the net?  That way you can always go back and find everything you ever saw.

How about for the classroom?  It allows a huge amount of HD video to be used in class.

The big problem now is one of network bandwidth.  With the amount of data that can be generated, we will now need a revolutionary increase in network speeds.  I think the only way to go next will be straight fiber.  There is a lot of work on this now but this is the choke point now and will be even more in the future.

Larger Hard Drives are not disruptive but it will drive other parts of the internet.  Awesome!

  • Massive increase in disk space in next few years

    tags: technology harddrive

    • Consistent capacity growth in hard disk drives (HDDs) has become something we take for granted
    • a new technology breathes new life into HDDs. HAMR will bring massive storage growth and propel the industry far beyond 100 TB.
    • the storage density of PMR disks was just over 100 GB/inch2 and the industry forecasted that PMR will reach about 1 TB/inch2 until it runs out of room.
    • Seagate SVP Mark Re told me that Seagate in fact believes that there will be just a few more PMR product generations and a new technology will be necessary within 3 to 5 years as PMR may reach its end just north of 1 Tb/inch2.
    • heat-assisted magnetic recording (HAMR)
    • Seagate currently expects a soft limit to arrive at about 50 Tb/inch2. If the 3.5” HDD form factor survives, then we should see PMR to top out at about 5-6 TB per drive. With roughly 50x the potential of PMR, HAMR should lead the way beyond 100 TB drives and possibly into the region of 200 – 300 TB in the 2020 to 2025 time frame.
    • Given the fact that the first HDD stored 4.4 MB on 50 24-inch disks, this is a truly stunning prospect. Imagine the storage capabilities of a 100 TB drive. 250,000,000 average MP3 songs or 250,000,000 12 MP photographs. Or 2000 completely filled Blu-ray discs or hundreds of 3D movies. While data volumes of content will continue to evolve, HDD capacity will evolve as well and it is reasonable to expect that single HDDs will be able to store the digital lives of multiple generations of a family.

  3. I’m a non-email deleter also. Nice to be able to go back and search for anything!

    • I’m using Outlook on XP though and the search just really stinks on it. But yeah, it is cool to be able to search everything. Thanks for commenting!
