With your new business card USB drive, also called a credit card USB, you will make an unforgettable impression. These memory cards are slim enough to fit into a wallet or back pocket and offer full-color imprints.
USB flash drives are storage devices that use flash memory as a storage medium. They are connected to a computer or other reader via the USB interface. USB flash drives are removable, offer fast read and write speeds, are rewritable, and are physically much smaller than an optical disc.
Flash drive and jump drive refer to the same storage device that connects to a USB port. There is no difference. They are also called thumb drives, pen drives, memory sticks, keychain drives, and USB drives.
The amount of data that a flash drive can hold depends on its storage capacity. Therefore, the memory capacity of a USB flash drive is one of the main criteria when choosing the right one for your business. Flash memory is measured in megabytes (MB), gigabytes (GB), and terabytes (TB). Commonly, memory can range from 128MB to 2TB.
You can print any logo, text, or image on bulk flash drives. Most models have two imprint areas so that you can put more information on them. Your organization, school, university, or club logo can be printed on one side and your contact details on the other.
The next step can be planning giveaways using bulk thumb drives. Customers are very attracted by the word "free." So using these branded USB flash drives as a freebie when customers purchase your products is a great idea.
You can also use custom branded USB sticks to thank those who attended your conference, promotional event, or presentation. This way, attendees of your event will remember your business and your presentation for longer.
The most important factor that affects the price of USB drives is the flash memory. If you buy in bulk, the wholesale price of custom USB Drives will be anywhere between $1.50 to $32.00 USD. Customization, shipping, and data preload are included in that price.
On a Mac computer, you must connect the flash drive, USB stick, or pen drive to the port. Flash drives are plug-and-play portable storage devices that utilize flash memory technology. Your computer should recognize these devices and display them on the desktop.
At USB Memory Direct, we offer bulk flash drives and other storage devices in many styles and colors. Our branding services allow you to customize your flash drive using heat stamp, laser engraving, or screen print techniques.
A USB flash drive (also called a thumb drive in the US, or a memory stick in the UK)[1][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[update], flash drives with anywhere from 8 to 256 gigabytes (GB[note 2]) were frequently sold, while 512 GB and 1 terabyte (TB[note 3]) units were less frequent.[4][5] As of 2018, 2 TB flash drives were the largest available in terms of storage capacity.[6] Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances (shelf storage time[note 4]).
The basis for USB flash drives is flash memory, a type of floating-gate semiconductor memory invented by Fujio Masuoka in the early 1980s. Flash memory uses floating-gate MOSFET transistors as memory cells.[9][10]
Inside the 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.[29]
Flash memory combines a number of older technologies, with lower cost, lower power consumption and small size made possible by advances in semiconductor device fabrication 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.
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.
The development of high-speed serial data interfaces such as USB made semiconductor memory systems with serially accessed storage viable, and the simultaneous development of small, high-speed, low-power microprocessor systems allowed this to be incorporated into extremely compact systems. Serial access requires far fewer electrical connections for the memory chips than does parallel access, which has simplified the manufacture of multi-gigabyte drives.
Computers access modern[update] flash memory systems very much like hard disk drives, where the controller system has full control over where information is actually stored. The actual EEPROM writing and erasure processes are, however, still very similar to the earlier systems described above.
Many low-cost MP3 players simply add extra software and a battery to a standard flash memory control microprocessor so it can also serve as a music playback decoder. Most of these players can also be used as a conventional flash drive, for storing files of any type.
Most USB flash drives weigh less than 30 g (1 oz).[32] While some manufacturers are competing for the smallest size,[33] with the biggest memory, offering drives only a few millimeters larger than the USB plug itself,[34] some manufacturers differentiate their products by using elaborate housings, which are often bulky and make the drive difficult to connect to the USB port. Because the USB port connectors on a computer housing are often closely spaced, plugging a flash drive into a USB port may block an adjacent port. Such devices may carry the USB logo only if sold with a separate extension cable. Such cables are USB-compatible but do not conform to the USB standard.[35][36]
Some file systems are designed to distribute usage over an entire memory device without concentrating usage on any part (e.g., for a directory) to prolong the life of simple flash memory devices. Some USB flash drives have this 'wear leveling' feature built into the software controller to prolong device life, while others do not, so it is not necessarily helpful to install one of these file systems.[40]
The memory in flash drives was commonly engineered with multi-level cell (MLC) based memory that is good for around 3,000-5,000 program-erase cycles.[41] Nowadays Triple-level Cell (TLC) is also often used, which has up to 500 write cycles per physical sector, while some high-end flash drives have single-level cell (SLC) based memory that is good for around 30,000 writes.[42] There is virtually no limit to the number of reads from such flash memory, so a well-worn USB drive may be write-protected to help ensure the life of individual cells.
Estimation of flash memory endurance is a challenging subject that depends on the SLC/MLC/TLC memory type, size of the flash memory chips, and actual usage pattern. As a result, a USB flash drive can last from a few days to several hundred years.[43]
Counterfeit USB flash drives are sometimes sold with claims of having higher capacities than they actually have. These are typically low capacity USB drives whose flash memory controller firmware is modified so that they emulate larger capacity drives (for example, a 2 GB drive being marketed as a 64 GB drive). When plugged into a computer, they report themselves as being the larger capacity they were sold as, but when data is written to them, either the write fails, the drive freezes up, or it overwrites existing data. Software tools exist to check and detect fake USB drives,[45][46] and in some cases it is possible to repair these devices to remove the false capacity information and use its real storage limit.[47]
Transfer speeds are technically determined by the slowest of three factors: the USB version used, the speed in which the USB controller device can read and write data onto the flash memory, and the speed of the hardware bus, especially in the case of add-on USB ports.
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.[50] 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).
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: 041b061a72
