What happens when you mix relentless curiosity, innovative engineering, and a massive amount of NAND flash? You calculate pi to 300 trillion digits—and break a world record doing it.
We recently worked with Linus and Jake from Linus Tech Tips to achieve something extraordinary: setting a new GUINNESS WORLD RECORDS® title for the Most Accurate Value of Pi1. This wasn’t just a feat of mathematics—it was a demonstration of the real-world power and reliability of KIOXIA flash storage at an unprecedented scale.
2.2 Petabytes of KIOXIA SSDs, Working Flawlessly for Over Seven Months
To handle the enormous compute and storage demands of the project, Linus and Jake built a high-performance cluster using more than two petabytes* of KIOXIA enterprise drives. The setup included our CM Series 30.72 terabyte (TB) and CD Series 15.36 TB NVMe™ SSDs—built for speed, endurance, and consistency under heavy workloads. WEKA® was the important software architecture for the system configuration, and WEKA’s data platform was featured in the video.
Despite running continuous compute operations at speeds exceeding 100 GB/s for nearly 7.5 months, the system reported zero SSD failures. For a project operating at the edge of performance for such a sustained period, this is a testament to the engineering behind our drives.
As Jake put it, “The reliability and performance of KIOXIA’s NVMe SSDs enabled us to run continuous, intensive compute operations without a single SSD failure.” That’s the kind of field validation that can’t be replicated in a test lab.
Why This Matters
This wasn’t just a fun exercise (though it was definitely fun). The same technologies that helped calculate 300 trillion digits of pi are the ones powering mission-critical applications in data centers, scientific computing, AI training, and beyond. Our SSDs are designed to thrive in data-heavy, performance-intensive environments—like this one.
We’re proud to support innovators and creators who push the limits of what’s possible, and we’re thrilled that we not only broke a world record but showcased the capabilities of KIOXIA storage in such a bold way.

*1 petabyte = 1 billion megabytes.

Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
