A USB flash drive (short for Universal Serial Bus-Based PC Flash Disk), also called a thumb drive or memory stick, is a small, portable and resilient data storage device which can be easily plugged into the USB port of a computer. The storage capacity has greatly risen over time; after being introduced to the market in late 2000, storage capacity rose from just a few gigabytes to a few hundred by 2016, with some even as high as a terabyte. By 2018, flash drives with a storage capacity of two terabytes had become available.
