The first USB Flash Drive that I ever reviewed on Legit Reviews was the 16MB DiskOnKey Pro made by a company called M-Systems. M-Systems was later acquired by SanDisk, which was just acquired this year by Western Digital. The 16MB DiskOnKey Pro was available for $19.99, was marketed as being able to hold 11 floppy disks worth of data and was powered by a 32-bit ARM7 CPU. The fact that it has a processor inside was important back then as it was the first portable USB storage drive that was driverless and was able to run additional applications like automatic boot features and automatic logon. Those were the first time those features were seen on a USB Flash Drive and since then millions of USB Flash drives have been produced and it's not a common device that most people have had the pleasure of using. The 16MB DiskOnKey Pro used the USB 1.1 host interface and was capable of up to 12 MBits/sec or 1.5 MB/s of performance.
