Pi calculated to 314,000,000,000,000 digits breaks world record

Technology review site

StorageReview has broken the world record by calculating Pi to 314 trillion digits. StorageReview also published details of the machine used to perform the calculation, claiming that it has made a breakthrough in terms of calculation speed and power efficiency.

StorageReview has attempted to calculate Pi using a custom-built server, and in March 2024, they set a new world record by calculating to 105 trillion digits.

He then broke the record in June 2024 by calculating pi to 202,112,290,000,000,000,000,000 digits , but in May 2025, a joint team of Kioxia and Linus Media Group announced that they had successfully calculated 300 trillion digits.

StorageReview attempted to break the record using a Dell PowerEdge R7725 .

The CPU is equipped with two 192-core AMD EPYC processors. The standard configuration of the PowerEdge R7725 uses air cooling fans, but this has been changed to a water cooling system. It also has a total of 1.5TB of DDR5 memory.

The y-cruncher software was used to calculate pi. The storage was packed with 40 Micron 6550 ION drives, with 34 dedicated to y-cruncher calculation processing. The remaining six SSDs were used to create a RAID 10 configuration, recording 314 trillion digits of pi.

The calculation was completed in 110 days without any downtime. The graph below shows the number of digits (vertical axis) and calculation time (horizontal axis) of all previous records for pi, showing that this record was achieved in less time than rivals such as Google and Kioxia. The calculation also required 4,304.662 kWh of electricity, making it far more efficient than other pi calculation machines.

StorageReview noted that the PowerEdge R7725 and Micron 6550 ION combination allowed the machine to run for 110 days without downtime, proving that a similar system could be effective for 'production science tasks that require months of continuous computation,' such as climate modeling, physical simulations, genomics pipelines, and AI training.
