The invention relates to a solid hard disk with a quick data self-destructing function, and belongs to the technical field of quick data destructing in solid storage. The solid hard disk with the quick data self-destructing function is characterized in that data of the solid hard disk is destructed by a soft data destructing manner and a hard data destructing manner; the soft data destructing manner is that a trigger switch applies a low-level pulse signal to destruct data in a hard disk controller so as to achieve formatting of stored contents; the hard data destructing manner is that a power conversion chip applies high pressure to an FLASH to damage the performance of a storage medium so as to achieve the purpose of destructing data; the two destructing manners are matched to achieve the quick data destructing function, and the potential risk of key data can be removed. The solid hard disk with the quick data self-destructing function is high in destruction speed, and simple to operate, and the cost of the solid hard disk is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of fast data destruction in solid-state storage, in particular to a solid-state hard disk with a fast data self-destruction function. Background technique [0002] With the development of computer technology, storage technology is also constantly improving, so there are higher requirements for storage capacity and read / write speed of storage media. As the main physical storage device of the computer, the hard disk plays an irreplaceable role, and the technical requirements are increasing day by day, especially the solid-state hard disk, because of its large storage capacity, high data read and write speed, and special environmental requirements such as adapting to vibration and turbulence, it is widely used in military and civilian industries. widely used in. [0003] In the weapon control system and the command system, a large amount of stored key data such as electronic charts, guidance video information,...
