Solid state disk capable of destroying and recovering data and method

Abstract

The invention discloses a solid state disk capable of destroying and recovering data. The disk comprises a front-end hard disk controller, a rear-end hard disk controller, a front-end flash memory module, a rear-end flash memory module, a destruction instruction input unit and a recovery instruction input unit, wherein a default forbidden interaction controller is connected between the front-end hard disk controller and the rear-end hard disk controller, and the front-end hard disk controller is used for formatting data in the front-end flash memory module when receiving an instruction sent bythe destruction instruction input unit; the rear-end hard disk controller is used for starting the interaction controller when receiving an instruction sent by the recovery instruction input unit; and the interaction controller is used for copying data in the rear-end flash memory module through the rear-end hard disk controller after the interaction controller is started, and copying the data tothe front-end flash memory module through the front-end hard disk controller. According to the method, the data can be destroyed and recovered, the data recovery process is simple and rapid, and thusthe convenience and usability of the data protection process are improved.

Description

technical field [0001] The invention relates to a solid-state hard disk, in particular to a solid-state hard disk capable of destroying and recovering data and a method thereof. Background technique [0002] With the continuous improvement of data value and the continuous development of storage technology, the importance of storage systems such as solid-state drives continues to increase, and data has become the core asset. As the storage space for data, the storage system is the last line of defense for data protection; as the storage system develops from local direct connection to networked and distributed, and is shared by many computers on the network, the storage system becomes more vulnerable to Attacks, relatively static storage systems are often the first choice for attackers to achieve the purpose of stealing, tampering or destroying data. If there are no storage security precautions, once the attacker successfully penetrates into the data storage system, the negati...

AI Technical Summary

Problems solved by technology

However, most of the existing solid-state hard disks only have the function of data destruction and do not have the function of data recovery. Once the data is destroyed, it cannot be recovered, or it needs a cumbersome process to recover, which has caused serious losses to users. Therefore, Unable to meet user needs
