1. Movement: movement includes a PCB + USB master chip + crystal + chip resistor, capacitor + USB interface + SMD LED (not all U disk has) + FLASH (flash memory) chip

2. Shell: According to the material classification, there are ABS plastic, bamboo, metal, leather, silicone, PVC software, etc.; classified by style, there are cards, pens, mini, cartoon, business, simulation, etc.; classified by function, there is encryption, Antivirus, waterproof, smart and so on.

U disk 3. For some special shape PVCU discs, special supporting packages are sometimes produced.

Compared to other portable storage devices (especially floppy disks), flash drives have many advantages: they take up less space and usually operate faster (USB 1.1, 2.0, 3.0), they store more data, and they may More reliable (because there is no mechanical equipment), disconnects during reads and writes without damaging the hardware (the floppy disk breaks as soon as it is read or written) and only loses data. This type of disk uses USB mass storage device standards and has built-in support for modern operating systems such as Linux, Mac OS X, Unix and Windows 2000, XP, and Win7. [3]

Flash drives usually use ABS plastic or metal housings and contain a small printed circuit board inside, allowing the flash drive to be small enough to fit into a pocket like a key ring charm or to be strung on a neckline. Only the USB connector protrudes out of the protective case and is usually covered by a small cover. Most flash drives use standard Type-A USB connectors, which allow them to be plugged directly into a USB port on a personal computer.

To access the data on the flash drive, the flash drive must be connected to the computer; either directly connected to the computer's built-in USB controller or a USB hub. The flash disk will only be turned on when it is plugged into the USB port, and the required power is also supplied by the USB connection. However, some flash drives (especially high-speed flash drives using the USB 2.0 standard) may require more power, so if connected to a USB hub like a built-in keyboard or screen, these flash drives will not work unless they are directly Plug in the controller (that is, the USB port provided by the computer itself) or an external USB hub. Some U-disks are composed of drivers and U-disks, so they must be resolved at the end (in DOS/win32 environments).
