KIOXIA and Linus Media Group Set World Record for Pi Calculation

New GUINNESS WORLD RECORDS Title for Most Accurate Value of Pi - 300 Trillion Digits Calculated Using KIOXIA NVMe™ SSDs

Kioxia Corporation, a world leader in memory solutions, today announced that it has collaborated with Linus Media Group, creator of Linus Tech Tips and other influential technology-focused YouTube^TM 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 Records¹.

KIOXIA SSD

The record-smashing computation was enabled by a high-performance storage cluster comprising 2.2 petabytes (PB)² of 30.72 terabyte (TB) CM Series and 15.36 TB CD Series PCIe^® NVMe^™-based solid-state drives (SSDs) from KIOXIA. These SSDs were configured in a network-attached storage environment connected to a dual-CPU compute server and ran for nearly seven and a half months.

Pi (π) represents the mathematical constant expressing the ratio of a circle’s circumference to its diameter. Its decimal representation extends infinitely without repeating. This new record significantly surpasses the previous official GUINNESS WORLD RECORDS benchmark of 62 trillion digits by a factor of nearly five.

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.

Notes:
¹As of April 2, 2025
²1 petabyte = 1 billion megabytes (for example, 1 petabyte is equivalent to approximately 300 million 3 MB images taken with a smartphone)

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.
