History and Origins
The first USB flash drive was developed in 2000 by IBM engineers M-Systems and Trek Technology. The original name for the device was “Pen Drive”, envisioned as a pen-shaped device that could plug into a USB port. When the device was licensed and first sold by IBM later that year, it was rebranded as the “DiskOnKey” as IBM wished to avoid confusion with pen computing devices. In 2000, IBM released the first commercial USB flash drive available to the public with an 8 MB storage capacity.
Over the next few years, several other manufacturers including Trek Technology, Lexar and Kingston Technology released their own USB flash drives. These early drives had storage capacities ranging from 8 MB to 256 MB. Many of the drives were made out of rugged metal housing which gave them better durability over floppy disks and early forms of flash memory storage. By 2003, USB flash drives rapidly gained popularity due to their small size, large capacity compared to floppy disks, and plug-and-play functionality with most computers.
Rise of USB Flash Drives
In the early 2000s, USB flash drives saw explosive growth and mass adoption. Some key factors driving the success of USB flash drives were:
- Increasing storage capacities – Early sizes of 32MB to 256MB grew to multiple gigabytes allowing storage of more data.
- Falling prices – Cost per megabyte of storage dropped dramatically making high-capacity drives affordable.
- USB 2.0 adoption – Faster USB 2.0 transfer speeds of up to 480 megabits/second.
- Compact rugged designs – Durable metal and plastic bodies allowed easy transport.
- Marketing – Clever marketing positioned drives as fashionable and convenient items.
By 2004, USB flash drives began outselling both floppy disks and CD-RWs as they offered much larger capacities for storing and transferring files between computers. At this time capacities ranged from 128MB on the low end to upwards of 1GB for high-end models. The most popular earlier brand of USB drive was the FlashDrive by Lexar. Other leading manufacturers included Kingston, SanDisk and Kanguru.
Evolution in Capacities
As technology improved, USB flash drives experienced rapid growth in storage capacities throughout the 2000s. Some notable milestones included:
- 2004 – First 4GB drives introduced
- 2005 – 8GB drives reach mainstream
- 2009 – First 32GB and 64GB drives
- 2010 – SanDisk releases first USB 3.0 drive with capacities over 100GB
- 2011 – First 128GB drives hit market
- 2013 – 256GB drives introduced
- 2016 – Kingston releases 1TB drive
- 2017 – 2TB drives introduced
This exponential growth allowed consumers to store exponentially more data, photos, music and media files on their USB drives. Today, mainstream USB drives range from 16GB to 128GB, with higher capacity drives up to 2TB also available.
