who introduce the first floppy disk in 1967
History of the floppy disk Work on a drive that led to the world's first floppy disk and disk drive began in 1967 at a San Jose (CA) IBM facility,[1] and introduced into the market in an 8-inch format in 1972. The more conveniently sized 5¼-inch disks were introduced in 1976, and became almost universal on dedicated word processing systems and personal computers.[2] This format was more slowly replaced by the 3½-inch format, first introduced in 1982. There was a significant period where both were popular.[3] A number of other variant sizes were introduced over time, with limited market success.
USB flash drive USB flash drives were invented at M-Systems, an Israeli company, in a US patent filed in April 5, 1999 by Amir Ban, Dov Moran and Oron Ogdan, all M-Systems employees at the time.[7] The product was announced by the company in September 2000, and was first sold by IBM in 8MB capacity starting December 15, 2000.[8]
