The advantage of USB Flash Drive

1. The use of USB is very simple and convenient

There are many types of USB flash drives. Strictly speaking, only flash drives with USB interfaces can be called USB flash drives. This means that most modern operating systems can read and write flash drives without installing additional drivers

The U disk is displayed as a block-like logic unit in the operating system, hiding the complex details required by the internal flash memory. The operating system can use any file system or block addressing method. You can also make a bootable USB flash drive to boot the computer. Current operating systems such as Linux, MacOSX, Unix and Windows2000, XP, win7 all have built-in support

When in use, there is no need for a drive, no external power supply, plug and play, hot plugging. After connecting to the host of the computer through the USB interface, it can be formatted, copied, deleted and other operations can be performed like ordinary hard disks. The data on the USB flash drive can be transferred to the computer, and the data on the computer can also be easily transferred to the USB flash drive. Can be removed or connected at any time. Realize portable mobile storage. The access speed is fast (about 15 times the speed of a floppy disk); the reliability is good, it can be erased and written up to 1 million times, and the data can be stored for 10 years

3. The U disk has good security

It hardly allows water or dust to penetrate, and it will not be scratched, which is a serious problem in old portable storage devices (such as compact discs and floppy disks). The solid-state storage design used by flash drives allows them to resist unintentional external impacts. These advantages make the flash drive very suitable for carrying personal data or work files from one place to another, such as from home to school or office, or generally need to be carried to and accessed in various places of personal data. . Since USB is almost ubiquitous in today’s personal computers, flash drives can be used everywhere. However, the small size of flash drives also makes them often misplaced, forgotten or lost
