Toshiba Quarter-Sized 4GB HDD
January 9th, 2006

Toshiba 4GB hard disk drive is so small so that Guinness Book of World Records recognized it as the world’s smallest hard disk drive (HDD). It measures 0.85″, slighty larger than a US$ quarter.
Apparently, Toshiba even have a plan to boost the same size hard disk to 10GB in the future. Really cool, Toshiba!
