About

USB flash drive (ie USB stick) is a storage device containing a flash memory with a built-in USB interface. They are generally portable, rewritable and much smaller than an optical disc. Most weigh less than 30 grams (1 ounce). Since its introduction in the late 2000s, its storage capacity has dwindled like almost any other computer storage device. NAME. As of March 2016, USB flash drives ranged in size from 8 to 256 GB with the most common units being 512 GB and 1 TB.

The most common uses for USB flash drives are storage, extra backup and computer file transfer. Compared to floppy disks or CDs, they are smaller, faster, more durable, and last longer with no moving parts. They are also smaller than floppy disks for electromagnetic interference and (unlike CDs) are unaffected by surface scratches.

However, as with any flash drive, data loss due to prolonged power outages and self-check failures makes long-term data storage inconvenient. Data storage capability is affected by controller firmware, internal data rate, and error correction algorithms.

In 2005, most computers and laptops had floppy disks in addition to USB ports, but floppy drives became obsolete due to the use of multiple USB ports and larger USB drive capacity compared to “1.44 MB” (1440 KB). 3.5 inch floppy disk.

USB flash drives use the USB mass storage device class standard, which of course is supported by modern operating systems such as Windows, Linux, macOS, and other systems such as Unix, as well as many BIOS-enabled ROMs. USB 2.0 compatible flash drives can store data faster and transfer more data than larger optical drives such as CD-RW or DVD-RW drives, can be read on many other systems such as Xbox One, PlayStation 4, DVD players and in-car entertainment. Portable devices such as smartphones և tablets are used, but an electronic SD card is more suitable for these devices due to the standard power factor that allows the device to be inserted without slipping.

A USB stick consists of a small printed circuit board with circuit elements – an electrically insulated USB connector – in a shielded plastic, metal or rubber enclosure that can be kept, for example, in a pocket or handbag. Some have an I/O LED that lights or flashes when present. The USB connector can be protected by a removable cover or by pulling from the motor frame, otherwise it will not be damaged if not protected.

Most flash drives use a standard USB Type-A connector that allows you to connect to a PC, but other interface drivers are available (for example, micro-USB or USB-C connectors). USB drives are powered by a computer via a USB connection. Some devices combine the functions of a portable media player and a USB flash drive. It only needs one battery when listening to music on the go.
