Features of USB flash drive

The biggest advantage of USB flash drive is: small and easy to carry, large storage capacity, cheap, reliable performance. Flash disk volume is very small, only thumb-like size, extremely light weight, generally in about 15 grams, especially suitable for carrying, we can hang it in front of the chest, hanging on the key chain, and even put into the wallet. General U disk capacity of 1G, 2G, 4G, 8G, 16G, 32G, etc., the price of the most common 4GB, for example, about 50 yuan can be bought. There is no mechanical device in the storage disk, which is extremely resistant to shock. In addition, the flash drive also has moisture and anti-magnetic, high and low temperature resistance and other characteristics, safety and
reliability is very good. * Flash disks hardly allow water or dust to seep in or get scratched, which were serious problems in older portable storage devices (e.g. CD-ROMs, floppy disks), etc. And the solid-state storage design used in flash drives allows them to resist unintentional external impacts. These advantages make flash drives ideal for carrying personal data or work files from one place to another, such as from home to school or office, or generally to various locations where personal data needs to be carried to and accessed. Since USB is almost ubiquitous in today's personal computers, flash drives can be used everywhere. However, the small size of flash drives also means that they are often misplaced, forgotten or lost. * Flash drives may be small, but they have a relatively large storage capacity. Most commercially available flash drives today can store more data than a single CD (700MB), and advanced ones can store more data than a double-sided dual-layer DVD (17GB).  Flash drives use the USB mass storage device category, which means that most modern operating systems can read and write to flash drives without the need for additional driver installation. Flash drives are displayed as block-style logical units inside the operating system, hiding the complex details required for internal flash memory. The operating system can use any file system or block addressing method. It is also possible to create a bootable USB flash drive to boot the computer. * Like other flash memory devices, flash drives have limits on the total number of reads and writes. A mid-range flash drive can read and write hundreds of thousands of times under normal use, but when the flash drive gets old, the writing process can be more time consuming. When we use flash drives to run applications or operating systems, we can't help but consider this. Some developers have written special versions of operating systems (e.g. Linux) or applications (e.g. Mozilla Firefox) for flash drives to address this feature and the capacity limitations. They are often optimized for space usage and store the staging disk in the computer's main memory rather than on the flash drive. * Many flash drives support a write-protection mechanism. This switch on the casing prevents the computer from writing or modifying the data on the disk.
Write protection prevents computer virus files from being written to the flash drive to prevent the spread of that virus. A flash drive without write protection becomes a way for multiple viruses to spread with features such as autorun. * Flash drives are more tolerant of external impacts than mechanical disks, but can still fail or lose data due to severe physical damage. In assembled computers, incorrect wiring of the USB connection port can also damage the flash drive's circuitry
