I live right in the valley of data centers, like 80% of internet traffic goes through us (a dangerous place!). I drove by one of them today, and later at home, while Googling stuff about data centers, stumbled upon the NSA’s data center in Bluffdale, Utah.
It serves as a data repository for the U.S. intelligence community. Capacity — something like 5 trillion terabytes. 5,000,000,000,000,000 gigabytes. Back in 2013, it was 100-1000 times less, but 12 years have passed, Moore’s Law and all that. Hard drives in data centers usually have a lifespan of 3-5 years. Meaning, since the launch of the data center, they have all been replaced several times with obviously greater capacity.
It is expected that the data center will be able to process “all types of communications, including the full content of private emails, mobile phone conversations, internet browsing, as well as all types of personal data: parking receipts, travel itineraries, purchases in bookstores, and data of other transactions made using digital technologies.”
The amount of data this facility is able to store is, of course, classified, but estimates “several yottabytes”. Yottabyte = 1000 zettabytes = 1,000,000 exabytes = 1 trillion terabytes. To store all the books ever written in any language would require just 400 terabytes.
In 2013 it consumed no less than 65 MW with a potential of 100 MW. Water — ~1.5–1.7 million gallons (5.7–6.4 million liters) per day for cooling servers. The water is treated with chemicals (to prevent corrosion) and discharged, leading to criticism in arid Utah — especially amid the record heat from 2022–2025 and the shortage of fresh water. There’s no closed-loop system, and it remains a “hot” topic in local discussions.
