To ensure this information isn't stolen as well, having a locked flash drive can keep anyone from viewing your files should the drive fall into the wrong hands. Tiny and portable, they easily slip into a pants or coat pocket, in a computer bag or purse, and come in a variety of shapes and sizes. External keypads add an additional level of security to portable memory, meaning a viewer must first input a numerical code to gain access to files. These in turn can be encrypted and password protected, deterring serious threats to personal security.
Not everyone wants every file they've ever created available in the cloud. It can put data at risk - not just from hackers or spammers or nosey bosses, but with some providers offering shady terms, you could lose the intellectual rights to anything uploaded. Having a portable memory drive means you don't have to sacrifice mobility for security, though, making flash drives an ideal solution for business people on the go.
The U3 company works with drive makers (parent company SanDisk as well as others) to deliver custom versions of applications designed for Microsoft Windows from a special flash drive; U3-compatible devices are designed to autoload a menu when plugged into a computer running Windows. Applications must be modified for the U3 platform not to leave any data on the host machine. U3 also provides a software framework for independent software vendors interested in their platform.
In addition to providing reliable storage for information, many of these products come with security software that protects your personal data if you lose your device. The software secures files with 128-bit AES encryption and requires a password to unlock the stored information. It also features a drag-and-drop user interface that simplifies transferring and securing your data.
Specially manufactured flash drives are available that have a tough rubber or metal casing designed to be waterproof and virtually "unbreakable". These flash drives retain their memory after being submerged in water, and even through a machine wash. Leaving such a flash drive out to dry completely before allowing current to run through it has been known to result in a working drive with no future problems. Channel Five's Gadget Show cooked one of these flash drives with propane, froze it with dry ice, submerged it in various acidic liquids, ran over it with a jeep and fired it against a wall with a mortar. A company specializing in recovering lost data from computer drives managed to recover all the data on the drive.[64] All data on the other removable storage devices tested, using optical or magnetic technologies, were destroyed.
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]
Optical storage devices are among the cheapest methods of mass data storage after the hard drive. They are slower than their flash-based counterparts. Standard 120 mm optical discs are larger than flash drives and more subject to damage. Smaller optical media do exist, such as business card CD-Rs which have the same dimensions as a credit card, and the slightly less convenient but higher capacity 80 mm recordable MiniCD and Mini DVD. The small discs are more expensive than the standard size, and do not work in all drives.
For computers set up to be bootable from a USB drive, it is possible to use a flash drive containing a bootable portable operating system to access the files of the computer, even if the computer is password protected. The password can then be changed, or it may be possible to crack the password with a password cracking program and gain full control over the computer. Encrypting files provides considerable protection against this type of attack.
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.
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]
Most USB-based flash technology integrates a printed circuit board with a metal tip, which is simply soldered on. As a result, the stress point is where the two pieces join. The quality control of some manufacturers does not ensure a proper solder temperature, further weakening the stress point.[77][78] Since many flash drives stick out from computers, they are likely to be bumped repeatedly and may break at the stress point. Most of the time, a break at the stress point tears the joint from the printed circuit board and results in permanent damage. However, some manufacturers produce discreet flash drives that do not stick out, and others use a solid metal uni-body that has no easily discernible stress point. SD cards serve as a good alternative to USB drives since they can be inserted flush.

USB flash drives are only limited by the cost of the storage space and the physical constraints of the drive. Some of the cheaper flash drives can store less than a gigabyte, but modern high-end flash drives can store as much as 1TB of data, about equivalent to a typical hard drive. A standard external USB drive can store or backup around 64GB, 128GB, 256GB, or 512GB of data. As storage space increases, USB flash drives have become proficient at storing massive files such as ultra high-definition videos that display at 4K or even 8K resolution.
A USB flash drive[note 1] is a data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable and much smaller than an optical disc. Most weigh less than 30 g (1 oz). Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. As of March 2016, flash drives with anywhere from 8 to 256 GB were frequently sold, while 512 GB and 1 TB units were less frequent.[2][3] As of 2018, 2 TB flash drives were the largest available in terms of storage capacity.[4] Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to last between 10 and 100 years under normal circumstances (shelf storage time[5]).
A recent development for the use of a USB Flash Drive as an application carrier is to carry the Computer Online Forensic Evidence Extractor (COFEE) application developed by Microsoft. COFEE is a set of applications designed to search for and extract digital evidence on computers confiscated from suspects.[48] Forensic software is required not to alter, in any way, the information stored on the computer being examined. Other forensic suites run from CD-ROM or DVD-ROM, but cannot store data on the media they are run from (although they can write to other attached devices, such as external drives or memory sticks).
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. The patent application was filed by M-Systems in April 1999.[6][1][7] Later in 1999, IBM filed an invention disclosure by one of its employees.[1] Flash drives were sold initially by Trek 2000 International, a company in Singapore, which began selling in early 2000. IBM became the first to sell USB flash drives in the United States in 2000.[1] The initial storage capacity of a flash drive was 8 MB.[7] Another version of the flash drive, described as a pen drive, was also developed. Pua Khein-Seng from Malaysia has been credited with this invention.[8] Patent disputes have arisen over the years, with competing companies including Singaporean company Trek Technology and Chinese company Netac Technology, attempting to enforce their patents.[9] Trek won a suit in Singapore,[10][11] but has lost battles in other countries.[12] Netac Technology has brought lawsuits against PNY Technologies,[13] Lenovo,[14] aigo,[15] Sony,[16][17][18] and Taiwan's Acer and Tai Guen Enterprise Co.[18]
“The DataTraveler's tiny metal frame and prominent key ring make it easily portable,” our tester said of this flash drive. He added, “Downloading files off the drive itself is fast and easy, at over 100 MB/s, and it's also one of the cheapest USB 3.0 flash drives you can get.” The downside? “While read speeds were fine, the DataTraveler struggles to actually copy files onto the drive,” our reviewer explained. “Despite supporting USB 3.0, it barely tops write speeds of 10 MB/s, and lacks any other features.” The takeaway: “We'd only recommend this product as a cheap way for business professionals to pass out digital content to clients, or for networking,” he stated.

USB flash drives have been integrated into other commonly carried items, such as watches, pens, and even the Swiss Army Knife; others have been fitted with novelty cases such as toy cars or Lego bricks. USB flash drives with images of dragons, cats or aliens are very popular in Asia.[36] The small size, robustness and cheapness of USB flash drives make them an increasingly popular peripheral for case modding.

If you are taking your data to the extreme ends of the Earth and need to go a step above and beyond to keep it safe, the rugged Corsair Flash Survivor Stealth 64-bit is the drive for you. Constructed with aircraft-grade aluminum housing and outfitted with a molded shock damping collar, this drive is meant to survive anything you can throw at it. It can even be submerged in up to 200 meters of water because of the EPDM (ethylene propylene diene monomer rubber) waterproof seal. With speeds at around 85 MB/s, this isn’t the fastest drive around, but its ruggedness is unparalleled.
Buying your flash drives in bulk may be a way to save in the long run depending on how many individual drives you need. Some brands or distributors may offer you discounts in an effort to move some of their inventories. eBay allows you to sort items by price or input your own custom price range. Using this feature may help you find the deal that works for you. Some standard price ranges you might find by default are the following:
Most USB flash drives do not include a write protection mechanism. This feature, which gradually became less common, consists of a switch on the housing of the drive itself, that prevents the host computer from writing or modifying data on the drive. For example, write protection makes a device suitable for repairing virus-contaminated host computers without the risk of infecting a USB flash drive itself. In contrast to SD cards, write protection on USB flash drives (when available) is connected to the drive circuitry, and is handled by the drive itself instead of the host (on SD cards handling of the write-protection notch is optional).
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.
