Kioxia and Linus Media Group Set World Record for Pi Calculation

Kioxia America, Inc. announced that it has collaborated with Linus Media Group, creator of Linus Tech Tips and other influential technology-focused YouTube channels, to set a new Guinness World Records title for the Most Accurate Value of Pi.

A groundbreaking 300 trillion digits were calculated and have been officially verified and confirmed by Guinness World Records ⁽¹⁾.

The record-smashing computation was enabled by a high-performance storage cluster comprising 2.2PB ^(*) of 30.72TB CM Series and 15.36TB CD Series PCIe NVMe-based SSDs from Kioxia. These SSDs were configured in a NAS environment connected to a dual-CPU compute server and ran for nearly seven and a half months.

“We knew breaking the Pi record with distributed network storage was going to be difficult – no one had really done it before due to the performance challenges associated with remote storage,” said Jake Tivy, writer and host, Linus Media Group. “Fortunately for us, the reliability and performance of Kioxia’s NVMe SSDs enabled us to run continuous, intensive compute operations at speeds up to 100+ GB/s for nearly seven months straight, without a single SSD failure.”

“Setting a new Guinness World Records title for the most accurate value of Pi is a monumental achievement, and showcases the capabilities and robustness of our NVMe SSDs,” said Alex Mei, VP corporate marketing, Kioxia America. “Working with Linus Media Group on this project, we demonstrated what our SSD technology can accomplish under sustained, high-intensity workloads. We’re proud to have achieved this record-breaking milestone with Linus and his team, and look forward to continuing to push the boundaries of flash memory and SSD technology.”

Pi (π) represents the mathematical constant expressing the ratio of a circle’s circumference to its diameter. Its decimal representation extends infinitely without repeating. While the community recognizes records of 100 trillion and even 202 trillion digits have also been performed, this new record surpasses those by nearly 50% and significantly surpasses the previous official Guinness World Records benchmark of 62 trillion digits by a factor of nearly 5.

The record-setting achievement was documented in a feature video released by the Linus Tech Tips YouTube channel, giving viewers a behind-the-scenes look at the project and revealing the final digit of the record-setting calculation: spoiler alert…the 300 trillionth digit of Pi is 5.
