The first google storage was made from LEGO!. In 1998 when Larry Page and Sergey Brin were PhD students at Stanford, they were working on the Digital Library Project. They needed a large amount of disk space to test the PageRank algorithm on world wide web data. At the time of their research, the largest hard drive sizes were 4 gigabytes so they assembled 10 of them into a low-cost cabinet made out of Lego. Two years later, the company had 5,000 PCs for searching and web crawling using LINUX.
