This drive’s small size won over our testers: “Its small profile allows it to stay plugged into a computer even when transporting it in a bag or case, which is not something most flash drives can claim,” one person said. Lifewire reviewers agree that the drive’s tiny footprint makes it much more likely to get lost, but they say its fast read speeds and convenient portability easily make up for that.
Counterfeit USB flash drives are sometimes sold with claims of having higher capacities than they actually have. These are typically low capacity USB drives which are 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,[43][44] and in some cases it is possible to repair these devices to remove the false capacity information and use its real storage limit.[45]
A USB flash drive, also commonly known as a thumb drive or a memory stick, is a type of portable data storage device that fits directly into a USB port. It can back up, store, and transfer important data and make that data available to other devices with USB ports. USB drives tend to favor speed and convenience over absolute storage space; discover the wide selection available on eBay.
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).

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]
^ Also known as a thumb drive, pen drive, gig stick, flash stick, jump drive, disk key, disk on key (after the original M-Systems DiskOnKey drive from 2000),[1] flash-drive, memory stick (not to be confused with the Sony Memory Stick), USB key, USB stick or USB memory. For an incomplete list of alternative names, see the list of redirects to this article.

The memory in flash drives is commonly engineered with multi-level cell (MLC) based memory that is good for around 3,000-5,000 program-erase cycles,[40] but some flash drives have single-level cell (SLC) based memory that is good for around 100,000 writes. 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.

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.

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.

High-security flash drives aren’t exactly a new concept. For as long as companies have been transferring confidential info via USB drives, there’s been a concern of keeping that info confidential. While you might be swayed by flashy gimmicks like fingerprint sensors and password keypads, these end up being too expensive and not overly powerful (with a few exceptions of course). But that’s why our security pick goes to the Kingston Data Traveler Vault.
We offer the most reliable and consistently top performing customizable, no minimum USB flash drives out there. With more than 25 styles and over 550 different looks, our drives are available in 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB capacities–with most available in USB 3.0 from 16GB and up. We’re so confident in the quality of our drives, each one includes a lifetime warranty.
These products use flash memory chips, a stable, high-density storage medium, to hold your data. They pack a huge amount of information into a compact form factor. Most thumb drives are less than 2 inches long and easily fit in a pocket, laptop bag or purse. Models with built-in covers protect physical connectors from damage, and select products feature rugged silicon and metal shells that enhance heat and water resistance.
