What is a Disk on Key?
Disk on key is another term for a USB flash drive.
More specifically, DiskonKey™ (without spaces) was the name of one of the first USB flash drives, and a claim to the first USB flash drive ever invented, patented by M-Systems and sold by IBM.
In April 1999, the Israeli company M-Systems filed a patent application titled “Architecture for a Universal Serial Bus-based PC flash disk.” This was granted to Amir Ban, Dov Moran, and Oron Ogdan in November 2000. In 2000, IBM began selling M-Systems’ 8-MB storage devices in the United States under the less-than-memorable name DiskOnKey.
