What is a flash drive

Portable storage (USB Flash Disk), also known as flash disk. Is the use of USB interface and flash memory (Flash Memory) technology combined with the convenience of portable appearance beautiful fashionable mobile memory. Flash Disk is Flash Memory as a medium, so it has the advantages of multiple erasable, fast speed and anti-magnetic, shockproof, moisture-proof. Flash disk generally includes flash memory (Flash Memory), control chip and shell. Flash drive using the popular USB interface, the volume is only the size of a thumb, weighing about 20 grams, no drive, no external power supply, plug and play, to achieve the exchange of files between different computers, storage capacity from 16MB ~ 2GB ranging to meet different needs.

Flash drive products are through the integration of flash memory chips, USB I/O control chip and become the product NAND as a storage medium SSD (Solid State Disk), can be applied to desktop computers, notebooks, mobile devices, game consoles and other hardware, accelerate the startup, performance, while reducing power consumption.

Solid State Disk (Solid State Disk, IDE FLASH DISK) is composed of a control unit and a storage unit (FLASH chip), simply put, it is an array of solid-state electronic storage chips and made of hard disk (the current maximum capacity of 32GB), solid-state hard disk interface specifications and definitions, functions and methods of use with the ordinary hard disk. The interface specification and definition, function and use of the ordinary hard disk is exactly the same. In terms of product form factor and size, SSDs are available in 3.5", 2.5" and 1.8" sizes.

Because the solid state hard disk does not have the rotating medium of the ordinary hard disk, and thus excellent shock resistance, while the working temperature is very wide, extended temperature electronic hard disk can work in -45 ℃ ~ +85 ℃. Widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, etc., navigation equipment and other fields.
