Macbooks require a USB Type-C device, which is where this swivel dual flash drive from Silicon Power comes in handy. It features a dual interface with USB Type-C and USB Type-A 3.0 ports on opposite ends of a compact device. The 360-degree swivel cap protects whichever connector is not in use and attaches easily to keychains. The C80 doesn’t require any special drivers or software to work; just plug it into the port and it is ready to go. But it has an optional file management app, which is a free and simple automatic file categorization that puts your work in the appropriate folders. Expect fast read and write speeds and 64 GB of storage to hold all your photos and files.
Flash drives are also cost-effective. You can securely store a few dozen gigabytes of data for less than $30, and these devices range in storage capacity, price and overall size - equal to the amount you're willing to invest. Some even have special features like lanyards, locks, belt clips and key fobs to make them easier to carry and keep track of.
A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case, which can be carried in a pocket or on a key chain, for example. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist. USB flash drives draw power from the computer via the USB connection. Some devices combine the functionality of a portable media player with USB flash storage; they require a battery only when used to play music on the go.
Floppy disk hardware emulators exist which effectively utilize the internal connections and physical attributes of a floppy disk drive to utilize a device where a USB flash drive emulates the storage space of a floppy disk in a solid state form, and can be divided into a number of individual virtual floppy disk images using individual data channels.
Lexar is attempting to introduce a USB FlashCard, which would be a compact USB flash drive intended to replace various kinds of flash memory cards. Pretec introduced a similar card, which also plugs into any USB port, but is just one quarter the thickness of the Lexar model.[85] Until 2008, SanDisk manufactured a product called SD Plus, which was a SecureDigital card with a USB connector.[86]
USB flash drives are often used for storage, data back-up and transfer of computer files. 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. Additionally, they are immune to electromagnetic interference (unlike floppy disks), and are unharmed by surface scratches (unlike CDs). Until about 2005, most desktop and laptop computers were supplied with floppy disk drives in addition to USB ports, but floppy disk drives became obsolete after widespread adoption of USB ports and the larger USB drive capacity compared to the 1.44 MB 3.5-inch floppy disk.

Original flash memory designs had very limited estimated lifetimes. The failure mechanism for flash memory cells is analogous to a metal fatigue mode; the device fails by refusing to write new data to specific cells that have been subject to many read-write cycles over the device's lifetime. 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. Originally, this potential failure mode limited the use of "live USB" system to special-purpose applications or temporary tasks, such as:

The SanDisk PRO gives you blistering speeds, offering 420 MB/s on the reading front and 380 MB/s on the writing end, which is 3–4x faster than what a standard USB 3.0 drive will offer. The sleek, aluminum casing is both super durable and very eye-catching, so you can bring it with you to your business meetings and look professional as well. The onboard AES, 128-bit file encryption gives you top-of-the-line security for your sensitive files. That USB 3.0 connection is also backward compatible with USB 2.0, so you won’t hit any snags with an older computer. SanDisk is so confident in the functionality of this little drive, that they’ve even backed it with a full lifetime warranty in case any issues befall it. Finally, there’s a file backup system you can download called RescuePRO that will let you recover lost files if needed.

Inside the plastic casing is a small printed circuit board, which has some power circuitry and a small number of surface-mounted integrated circuits (ICs).[citation needed] Typically, one of these ICs provides an interface between the USB connector and the onboard memory, while the other is the flash memory. Drives typically use the USB mass storage device class to communicate with the host.[28]

A minority of flash drives support biometric fingerprinting to confirm the user's identity. As of mid-2005,[needs update] this was an expensive alternative to standard password protection offered on many new USB flash storage devices. Most fingerprint scanning drives rely upon the host operating system to validate the fingerprint via a software driver, often restricting the drive to Microsoft Windows computers. However, there are USB drives with fingerprint scanners which use controllers that allow access to protected data without any authentication.[70]
You can get USB 3.0 speed in a compact and durable metal USB drive from Kingston for under $10.
