Flash drives implement the USB mass storage device class so that most modern operating systems can read and write to them without installing device drivers. The flash drives present a simple block-structured logical unit to the host operating system, hiding the individual complex implementation details of the various underlying flash memory devices. The operating system can use any file system or block addressing scheme. Some computers can boot up from flash drives.
Some organizations forbid the use of flash drives, and some computers are configured to disable the mounting of USB mass storage devices by users other than administrators; others use third-party software to control USB usage. The use of software allows the administrator to not only provide a USB lock but also control the use of CD-RW, SD cards and other memory devices. This enables companies with policies forbidding the use of USB flash drives in the workplace to enforce these policies. In a lower-tech security solution, some organizations disconnect USB ports inside the computer or fill the USB sockets with epoxy.
Flash drives can be defragmented. There is a widespread opinion that defragmenting brings little advantage (as there is no mechanical head that moves from fragment to fragment), and that defragmenting shortens the life of the drive by making many unnecessary writes.[37] However, some sources claim[38] that defragmenting a flash drive can improve performance (mostly due to improved caching of the clustered data), and the additional wear on flash drives may not be significant.
The advent of USB 3.0 makes data transfers over ten times faster than USB 2.0. If you have USB 3.0 port on your device, and you transfer files on a regular basis, the added speed on the PNY flash drive can be a big boost for getting things done (Even if you have a USB 2.0 port, you can still use USB 3.0, but you won’t get the same speeds). Pros: Fastest file transfers of any of the options. Cons: Some found the built-in external cover difficult to move.   Image Courtesy of Amazon
Also, HP has introduced a USB floppy drive key, which is an ordinary USB flash drive with additional possilibility for performing floppy drive emulation, allowing its usage for updating system firmware where direct usage of USB flash drives is not supported. Desired mode of operation (either regular USB mass storage device or of floppy drive emulation) is made selectable by a sliding switch on the device's housing.[51][52]
Our tester highly recommended this flash drive for iOS mobile users: “The iXpand is a great resource for backing up media files and for expanding storage, as well as transferring files to a PC.” He added, “The Drive App is easy to navigate and copy files with, as well as operate the camera and play music and video files.” On the other hand, our reviewer reported, “The 30 MB/s write speed on PC is far from horrible but definitely slow for the asking price, and we calculated only about a 12 MB/s when connected to an iOS device.” He ultimately concluded, “A slightly cheaper price would make it the surefire winner in the Lightning connector category.”

This depends on the programs. Most programs will situate their contents in multiple locations, so if it's on your computer, you'll need to know where all of a program is stored. It can be easier to download the program from scratch again as it brings in all of the needed content for you. If you are trying to transfer from a computer, at the very least be sure to capture the EXE, Application and Java files; however, there are usually many other files too. Also, the programs will differ between operating systems (for example, EXE is Windows, while .app is Mac). End answer: it can be done but it's easier if you can download the program afresh.

Hardware designers later developed EEPROMs with the erasure region broken up into smaller "fields" that could be erased individually without affecting the others. Altering the contents of a particular memory location involved copying the entire field into an off-chip buffer memory, erasing the field, modifying the data as required in the buffer, and re-writing it into the same field. This required considerable computer support, and PC-based EEPROM flash memory systems often carried their own dedicated microprocessor system. Flash drives are more or less a miniaturized version of this.

Apple smart products don’t come with USB ports, so you will need a backwards compatible drive that can also plug into lightning devices. This thumbdrive from SanDisk is designed for ease of use with iPhones and iPads, thanks to a curbed plastic connector that fits behind the back of the screen. It has high-speed USB 3.0 transfer speeds and can hold over 7,200 photos or 8,000 songs. It has automatic photo backup and contact transfer to help free up space on your devices without having to deal with the slow upload speeds.
The world is becoming increasingly virtual, which means fewer people print documents unnecessarily and opt to share them electronically instead. Rather than spend time and resources on information packs, why not use custom USB flash drives to provide your audience with the information they need? Our wholesale flash drives can be customized with your logo or brand name for a personal touch they can remember you by.
Unlike solid-state memory, hard drives are susceptible to damage by shock (e.g., a short fall) and vibration, have limitations on use at high altitude, and although they are shielded by their casings, they are vulnerable when exposed to strong magnetic fields. In terms of overall mass, hard drives are usually larger and heavier than flash drives; however, hard disks sometimes weigh less per unit of storage. Like flash drives, hard disks also suffer from file fragmentation, which can reduce access speed.

You can imprint USB drives with logos for your school, or use it as a gift to employees, or guests at the wedding.
When used in the same manner as external rotating drives (hard drives, optical drives, or floppy drives), i.e. in ignorance of their technology, USB drives' failure is more likely to be sudden: while rotating drives can fail instantaneously, they more frequently give some indication (noises, slowness) that they are about to fail, often with enough advance warning that data can be removed before total failure. USB drives give little or no advance warning of failure. Furthermore, when internal wear-leveling is applied to prolong life of the flash drive, once failure of even part of the memory occurs it can be difficult or impossible to use the remainder of the drive, which differs from magnetic media, where bad sectors can be marked permanently not to be used.[74]
Some manufacturers, aiming at a "best of both worlds" solution, have produced card readers that approach the size and form of USB flash drives (e.g., Kingston MobileLite,[65] SanDisk MobileMate[66]) These readers are limited to a specific subset of memory card formats (such as SD, microSD, or Memory Stick), and often completely enclose the card, offering durability and portability approaching, if not quite equal to, that of a flash drive. Although the combined cost of a mini-reader and a memory card is usually slightly higher than a USB flash drive of comparable capacity, the reader + card solution offers additional flexibility of use, and virtually "unlimited" capacity. The ubiquity of SD cards is such that, circa 2011, due to economies of scale, their price is now less than an equivalent-capacity USB flash drive, even with the added cost of a USB SD card reader.

Flash memory combines a number of older technologies, with lower cost, lower power consumption and small size made possible by advances in microprocessor technology. The memory storage was based on earlier EPROM and EEPROM technologies. These had limited capacity, were slow for both reading and writing, required complex high-voltage drive circuitry, and could be re-written only after erasing the entire contents of the chip.
On the more practical side our flash drives, also called thumbdrives or memory sticks are available in memory capacities from 64MB to 256GB. With memory capacities like that, we certainly have the options to cover whatever your data storage requirements may be. For more information on data storage capacities, check out our USB Flash Drive Capacity Guide.
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]

With their paper-slim profiles, Ultrabooks and tablets are barely thick enough for a USB port. That's why some of the bulkier drives on this list are not ideal for those devices. Meanwhile, Samsung’s Fit drives are slim and compact, about the size of your thumb nail. This unobtrusive storage is constructed with a metal casing that is resistant to the elements and NAND flash technology. With USB 3.0 tech you can expect fast read speeds, while the price is easy to stomach. Just make sure to attach it to a lanyard, so you don't lose it.
Like all flash memory devices, flash drives can sustain only a limited number of write and erase cycles before the drive fails.[71][unreliable source?][72] This should be a consideration when using a flash drive to run application software or an operating system. To address this, as well as space limitations, some developers have produced special versions of operating systems (such as Linux in Live USB)[73] or commonplace applications (such as Mozilla Firefox) designed to run from flash drives. These are typically optimized for size and configured to place temporary or intermediate files in the computer's main RAM rather than store them temporarily on the flash drive.
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).
Its a "branded" flash drive, so all our flash drives have imprint areas or laser etching that will make your logo pop! Whatever your event or program, there is likely a style of USB flash drive with an imprint area that provides just the right surface to make our images stand out. From 1 - 4 color spot to full-color process (try this on the credit card style drives!) your imprint will look fantastic.
"Nice device for bulky files....I have 2 of these flash drives and it's more convenient for me to store backups of my most important files on 2 of these flash drives than an external drive because it's easier for me to transfer my data files between 3 devices, carry the drive around in my pocket, and the transfers are easy and fast since it's USB 3.0"
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.

Flash drives are often measured by the rate at which they transfer data. Transfer rates may be given in megabytes per second (MB/s), megabits per second (Mbit/s), or in optical drive multipliers such as "180X" (180 times 150 KiB/s).[19] File transfer rates vary considerably among devices. Second generation flash drives have claimed to read at up to 30 MB/s and write at about half that rate, which was about 20 times faster than the theoretical transfer rate achievable by the previous model, USB 1.1, which is limited to 12 Mbit/s (1.5 MB/s) with accounted overhead.[20] The effective transfer rate of a device is significantly affected by the data access pattern.[21]
