Some types of flash drives have multiple connection options built into them, giving them an X shape. Lightning: A few flash drives contain a Lightning connector instead of a USB connector, enabling you to use the flash drive with newer Apple mobile devices, like iPads or iPhones. Micro USB: This connector is smaller than USB Type-C and shows up on mobile devices more often than computers because of its size. USB Type-C: USB Type-C is the largest connector option among USB standards, and it’s the most common on computers as well as on flash drives. However, you occasionally will see a few other options for connecting a flash drive. Most flash drives use the most common USB Type-C connector. USB ports are so common on so many types of devices that using USB flash drives gives you a lot of versatility. The vast majority of flash drives make use of a USB connection to share data with other devices. The flash drive needs electrical power to read and write data, but it works so well because it holds the zero or one setting in the cell (the data) even after you’ve removed the drive from its power source.īestReviews Flash drive connection options The method of application of an electrical charge between the transistors determines whether the cell has a zero or a one stored in it. Each section of the grid, called a cell, contains two transistors that work together to store a bit of data. To store individual bits of data, the silicon in the flash drive uses a grid layout. Flash memory requires no moving mechanical parts, and the flash drive has no moving parts either.
