Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts.
While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity and transfer speeds, such as USB flash drives, flash storage cards, portable external hard disk drives, optical discs, and storage available through computer networks such as cloud storage.

Flash memory

flashNANDFlash ROM
A USB flash drive is a data storage device that includes flash memory with an integrated USB interface.
The NAND type is found primarily in memory cards, USB flash drives, solid-state drives (those produced in 2009 or later), and similar products, for general storage and transfer of data.

USB mass storage device class

USB mass storageUSB mass storage deviceMSC
USB flash drives use the USB mass storage device class standard, supported natively by modern operating systems such as Windows, Linux, macOS and other Unix-like systems, as well as many BIOS boot ROMs.
Because of its relative simplicity, the most-common file system on embedded devices such as USB flash drives, cameras, or digital audio players is Microsoft's FAT or FAT32 file system (with optional support for long filenames).

M-Systems, an Israeli company, were granted a US patent on November 14, 2000, titled "Architecture for a [USB]-based Flash Disk", and crediting the invention to Amir Ban, Dov Moran and Oron Ogdan, all M-Systems employees at the time.
Dov Moran (דב מורן; born 1955) is an Israeli entrepreneur, inventor and investor, best known as the inventor of the USB memory stick, and one of the most prominent Israeli hi-tech leaders in the world.

Optical disc drive

USB drives with USB 2.0 support can store more data and transfer faster than much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox One, PlayStation 4, DVD players, automobile entertainment systems, and in a number of handheld devices such as smartphones and tablet computers, though the electronically similar SD card is better suited for those devices.
USB flash drives, high-capacity, small, and inexpensive, are suitable where read/write capability is required.

Disk formatting

However, because a flash drive appears as a USB-connected hard drive to the host system, the drive can be reformatted to any file system supported by the host operating system.
Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use.

Read-only memory

, NAND has partially achieved this goal by offering throughput comparable to hard disks, higher tolerance of physical shock, extreme miniaturization (in the form of USB flash drives and tiny microSD memory cards, for example), and much lower power consumption.

USB flash drive security

In some cases a secure USB drive may use a hardware-based encryption mechanism that uses a hardware module instead of software for strongly encrypting data.
USB flash drive products have been on the market since 2000, and their use is increasing exponentially.

Wear leveling

Premature failure of a "live USB" could be circumvented by using a flash drive with a write-lock switch as a WORM device, identical to a live CD.
The functionality of a live CD is also available with a bootable live USB flash drive, or an external hard disk drive connected by USB.

Encryption

The use of biometrics and encryption is becoming the norm with the need for increased security for data; on-the-fly encryption systems are particularly useful in this regard, as they can transparently encrypt large amounts of data.
Encryption can be used to protect data "at rest", such as information stored on computers and storage devices (e.g. USB flash drives).
