External flash drives use what's known as "solid-state" storage, which can store, back up, and retrieve data using only electronic circuits. Solid-state drives do not contain any moving mechanical parts, which enables them to access data quickly and easy. A typical flash drive allows up to 100,000 write/erase cycles before the integrity of the data starts to degrade. This translates to around a 10-year lifespan, depending on how much it is used.
With wide deployment(s) of flash drives being used in various environments (secured or otherwise), the issue of data and information security remains important. 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. 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. IEEE 1667 is an attempt to create a generic authentication platform for USB drives. It is supported in Windows 7 and Windows Vista (Service Pack 2 with a hotfix).[47]
Floppy disk drives are rarely fitted to modern computers and are obsolete for normal purposes, although internal and external drives can be fitted if required. Floppy disks may be the method of choice for transferring data to and from very old computers without USB or booting from floppy disks, and so they are sometimes used to change the firmware on, for example, BIOS chips. Devices with removable storage like older Yamaha music keyboards are also dependent on floppy disks, which require computers to process them. Newer devices are built with USB flash drive support.
The various writable and re-writable forms of CD and DVD are portable storage media supported by the vast majority of computers as of 2008. CD-R, DVD-R, and DVD+R can be written to only once, RW varieties up to about 1,000 erase/write cycles, while modern NAND-based flash drives often last for 500,000 or more erase/write cycles. DVD-RAM discs are the most suitable optical discs for data storage involving much rewriting.
Many people rely exclusively on the cloud for storing their data; it’s convenient and you can get a lot of storage for free. While storing data online certainly has its advantages, it also has serious drawbacks. The most obvious is security. Anything that is kept online is susceptible to security breaches, and news stories about many of the largest corporations suffering hacks only confirms that our online lives are not as safe as we may like.
Buoyed by its rocket-like speeds, the Extreme Go lives up to its name by transferring a 4K movie in less than 40 seconds — that's nearly 35 times the speed of a USB 2.0 drive and thanks to USB 3.1 hardware. Beyond its fast operation, the Sandisk looks as good as it performs with a sleek and slim package that's 2.79 x 0.84 x 0.45 inches in size and weighs only 4.8 ounces. The retractable connector makes it easy to store when not in use and it is backward compatible with any USB 3.0 or USB 2.0 port. Tucked inside its diminutive profile is a choice of 64GB or 128GB of storage capacity and it comes complete with data storage recovery in the event of an accidental file deletion.
A drawback to the small size of flash drives is that they are easily misplaced or otherwise lost. This is a particular problem if they contain sensitive data (see data security). As a consequence, some manufacturers have added encryption hardware to their drives, although software encryption systems which can be used in conjunction with any mass storage medium will achieve the same result. Most drives can be attached to keychains or lanyards. The USB plug is usually retractable or fitted with a removable protective cap.
Third generation USB flash drives were announced in late 2008 and became available in 2010.[citation needed] Like USB 2.0 before it, USB 3.0 dramatically improved data transfer rates compared to its predecessor. The USB 3.0 interface specified transfer rates up to 5 Gbit/s (625 MB/s), compared to USB 2.0's 480 Mbit/s (60 MB/s).[citation needed] By 2010 the maximum available storage capacity for the devices had reached upwards of 128 GB.[7] USB 3.0 was slow to appear in laptops. As of 2010, the majority of laptop models still contained the 2.0.[23]
The New York-based Human Rights Foundation collaborated with Forum 280 and USB Memory Direct to launch the "Flash Drives for Freedom" program.[80][81] The program was created in 2016 to smuggle flash drives with American and South Korean movies and television shows, as well as a copy of the Korean Wikipedia, into North Korea to spread pro-Western sentiment.[82][83]
Some value-added resellers are now using a flash drive as part of small-business turnkey solutions (e.g., point-of-sale systems). The drive is used as a backup medium: at the close of business each night, the drive is inserted, and a database backup is saved to the drive. Alternatively, the drive can be left inserted through the business day, and data regularly updated. In either case, the drive is removed at night and taken offsite.
In January 2013, tech company Kingston, released a flash drive with 1 TB of storage.[24] The first USB 3.1 type-C flash drives, with read/write speeds of around 530 MB/s, were announced in March 2015.[25] As of July 2016, flash drives within the 8 to 256 GB were sold more frequently than those between 512 GB and 1 TB units.[2][3] In 2017, Kingston Technology announced the release of a 2-TB flash drive.[26]

Motherboard firmware (including BIOS and UEFI) can be updated using USB flash drives. Usually, new firmware image is downloaded and placed onto a FAT16- or FAT32-formatted USB flash drive connected to a system which is to be updated, and path to the new firmware image is selected within the update component of system's firmware.[49] Some motherboard manufacturers are also allowing such updates to be performed without the need for entering system's firmware update component, making it possible to easily recover systems with corrupted firmware.[50]
Modern devices are thinner and lighter, and the Type-C connector is a plug format designed to work with these products. In addition to being smaller than a standard USB plug, Type-C connectors are reversible, so they're easier to use. Some USB flash drives include both a traditional plug and a Type-C connector. These products are ideal for transferring files between computers and portable devices such as smartphones or tablets.
