USB flash drive(Universal Serial Bus flash drive)is a small portable flash memory storage device using the USB interface,full name USB flash drive,is a kind of USB(Universal Serial Bus,Universal Serial Bus)interface without the need for a physical drive miniature high-capacity mobile storage products,through the USB interface and computer connection,to achieve plug and play,USB flash disk name comes from its shape similar to the traditional“U”lock,and it is small and portable,large storage capacity,so the name.Connected to the computer through the USB interface to achieve plug and play,the name of the USB memory stick comes from its shape is similar to the traditional“U”lock,and it is small and portable,large storage capacity,hence the name.
USB flash drive is mainly composed of a master control chip,flash memory chip(Flash Memory),USB interface and shell and other parts.The main control chip management and transmission of data,equivalent to the USB flash drive“brain”,which is responsible for coordinating the flash memory chip and the USB interface between the data read and write operations.
USB Flash chip is used to store data media,data in the form of binary stored in the flash chip transistor.USB interface is used to connect to computers and other devices to achieve data transmission and power supply.
USB interface:used to connect with the USB port of the computer or other devices.
USB Flash Drive Chips:used to store data,common storage types are NAND flash memory.
Master chip:responsible for data reading and writing,storage management and communication with the computer.
Case:protects the internal components while providing a portable shape and size.
-This is the most basic use of USB flash drives.Users can copy files from the computer,such as documents,pictures,music,videos,etc.,to the USB flash drive for storage.For some important data,such as the company’s financial statements,personal resume,etc.,can also play a backup role to prevent computer hard disk damage or data loss.
-USB flash drive can be used to make a system installation disk.For example,when the computer’s operating system fails and needs to be reinstalled,you can boot the computer and perform system installation by making a USB flash drive with operating system installation files.At the same time,some computer maintenance tools,such as disk inspection tools,data recovery tools,etc.can also be placed on a USB flash drive to facilitate maintenance operations on different computers.
-It can be used to transfer software between different computers.For example,in the absence of network connection,store the installation package of a software on a USB flash drive and then copy it to another computer for installation.For some software that is not allowed to be downloaded through the network,or in the environment of slow network speed,the USB flash drive is a good software transfer tool.
Portability:compact size,light weight,easy to put into the pocket or bag.
USB flash drive is small in size,usually only a few centimeters long,in various shapes,such as rectangular,round,etc..It can be easily hung on a keychain or put in a purse or pocket,making it easy for people to carry large amounts of data anywhere,anytime.For example,a USB flash drive with a capacity of 32GB may only measure about 60mm long,20mm wide,and 10mm high,yet it is able to store thousands of photos,a large number of documents,or multiple movies.
Large storage capacity:from a few GB to hundreds of GB,to meet the needs of different users.
With the development of technology,the capacity of USB flash drives has been increasing.From a few MB in the early days to several GB,dozens of GB or even several TB,which allows users to store a wide variety of files,such as office documents,high-definition videos,large software installation packages,etc.For example,for designers,a large storage capacity can be used to store a variety of files.For example,for designers,a high-capacity USB flash drive can be used to store high-resolution design materials,such as dozens of gigabytes of PSD(Photoshop documents)files.
Plug and play:no additional drivers,plug into the computer USB port can be automatically recognized and used.
The USB flash drive is very easy to use and it supports hot-swapping.When you insert the USB flash drive into the USB port of the computer,the computer system will generally automatically recognize and install the appropriate driver(in most common operating systems such as Windows,macOS,etc.),and then you can read and write the data in the USB flash drive like accessing a local hard disk.There is no need for complex installation and setup process like traditional storage devices.
Read and write speed:With the development of technology,the read and write speed of the USB flash disk is getting faster and faster,suitable for transferring large amounts of data.
Flash memory chips have the characteristics of non-volatile,that is,the data will not be lost after power failure.This makes USB flash drives a reliable data storage device.As long as the flash memory chip itself is not physically damaged,the data stored on it can be kept for a long time.For example,users can back up important files on the USB flash drive,even if the computer fails or power outage,the data in the USB flash drive is still safe.
support for a variety of operating systems,such as Windows,macOS,Linux and so on.
