Beijing Dianthus offers three levels of SSD data one-click destruction solution

With the continuous deepening and expansion of SSD applications, some systems that require special data security requirements can quickly destroy data stored in SSDs in a very short period of time. Once a key is destroyed, data stored in SSDs cannot be completely saved. It is restored to protect the user's information security. To meet these demands, Beijing Shizhu launched industrial-grade and military-grade SATA electronic disks and PMC/XMC memory cards with a secure erase function. By using an external trigger button, one-key data destruction can be achieved. The destruction time can be as short as 3 seconds. After the secure erase is performed, the data of the SSD solid state disk or memory card is completely destroyed and cannot be recovered, but the SSD solid state disk or memory card can still be used again.

The secure erasing function is divided into three levels: encryption block erasure, encryption block and physical block erasure, and military erasure, and the degree of erasure is enhanced in turn. These three levels of secure erasure ensure that the data is erased. Unrecoverable, effectively preventing data leakage and making your data more secure. The three types of secure erase work as follows:

Encryption Block Erase: Mainly erases various mapping tables of the SSD controller, such as bad block management, dynamic mapping table, static mapping table, and fragment recovery table. Data erasure is caused by erasing various mapping tables of NAND Flash. Recovery, erase time is less than 3s. After the encryption block is erased, the mapping data is completely lost and the SSD data is completely unrecoverable.
Encryption block and physical block erasure: In addition to the encryption block erasure, Erase operations are performed on all NAND Flash blocks to ensure that all NAND Flash memory cell values ​​are restored to the factory state, ie, 0xFF, and the erase speed is 3 GB/s. After the encryption block and the physical block are erased, the mapping data and the physical block data are completely lost, and the SSD data is completely unrecoverable.
Army erasure: Army erasure consists of encryption block erasure, physical block erasure, NAND Flash memory unit Overwrite, encryption block erasure and physical block erasure, NAND Flash memory cell Overwrite is one for NAND Flash. Page writes specific data or random data. After the military erasing is performed, the mapped data is completely lost. All Blocks of the NAND Flash perform an Erase operation. All pages of the NAND Flash perform specific or random data write operations, and the SSD data is completely unrecoverable.

The above three types of secure erase do not cause any physical damage to the SSD itself, and can be safely used safely. This function is particularly suitable for industrial or military units that require high data security.
