Backblaze Expects HDD Storage Costs to Hit One Cent per GB by 2025

Cloud storage specialist Backblaze expects the downward price trend for HDDs to continue. While that may sound like a self-fulfilling prophecy, Backblaze goes further than simply noting a well-known HDD pricing trend: the company expects consumers to be able to purchase storage space at a previously unseen $0.01 per GB ratio as soon as 2025. As least, that's the story according to Backblaze's Andy Klein, the company's Principle Storage Cloud Storyteller. With 253,500 HDDs bought throughout its lifetime, Backblaze certainly has the numbers from which to weave a story.

Andy Klein analyzed Backblaze's HDD purchases throughout the time the company has been operating, starting in 2009. At that time, Backblaze's HDD acquisitions were averaging out at a storage cost of around $0.114/GB (for capacities between 1TB and 2TB per HDD). By 2017, with the advent of 8TB HDDs, that cost had fallen by 73% down to $0.03/GB; in the intervening years and with no small thanks to ever denser HDDs culminating in the 16TB HDDs the company currently acquires, Backblaze has almost doubled its density/dollar equation by reaching $0.014/GB.

    16TB drives going for $250 right now. That's 1.5 cents/GB. So this isn't that far fetched.

    But when will it hit $0.01 per 1 GiB
    We know that Storage Makers love touting GB instead of GiB

    I agree. I just picked up a WD Blue 8TB from Walmart for $120 or 1.5c per GB.

    What I'm waiting for is prices to come down and storage sizes to go up on 2.5" drives... I don't need 22TB and I don't need a noisy 3.5" drive right next to my bed keeping me awake at night. But it seems like 2.5" drives have been stuck at 5TB for some time now, and Black Friday prices were still above what I paid the last time I needed to add 5TB to my collection at the start of this year. Needless to say, I didn't buy any, but in a few weeks I'll have to start taking extraordinary measures to keep from running out of space.

    Wow, they don't just have Cloud Storytellers, but Principal Cloud Storytellers!

    ...or, maybe that's not a spelling error, but he's actually a Story Teller about Cloud Principles?

    🤣

    they still serve and will continue to serve their purposes for cold or non-critical storage requirements due to their higher storage density compared to SSDs.
    @Francisco Alexandre Pires , the main issue with using SSDs for cold storage is that if you leave a modern QLC SSD disconnected in a drawer, for a couple years, it'll lose its contents. HDDs have much better power-off data retention characteristics*.

    I have an e-reader that I bought in 2019, meaning it probably uses TLC storage. I once left it turned off and unused for 6 months, and all of my books were gone, when I recharged it and turned it on again.

    * For longevity, you still can't beat the highest-grade optical media.

    Eh, but if you click the arrow in the image area, to see the 3rd image, it seems to be asymptotically approaching $0.0133 / GB. And then there's inflation, that will affect new drives.
