TCG Opal 安全子系統類別（SSC）2.0 是一組針對自我加密驅動器的規範，提供安全管理標準的層次結構，以保護數據免受盗竊和篡改。安全功能包括基於硬體的資料加密、啟動前身份驗證（PBA）和 AES-128/256 資料加密，以保護靜態數據的機密性。

專為SSD和記憶卡設計的清除解決方案，確保在SSD或記憶卡需要被處置或重新使用時，敏感資料無法被恢復或擷取。透過確保敏感資料的任何遺留部分都不存在，安全擦除是擁有高度安全需求的政府和企業應用的理想解決方案。

Hardware Secure Erase wipes out all user data, overwrites all locations, and prevents the retrieval or recovery of erased data. This feature is activated using the general-purpose input/output (GPIO) connector to trigger a Fast Erase or Fast Erase + Purge (overwrite) for all flash physical blocks containing user data, such as user data, spare, wear leveling, and bad blocks, as well as all flash blocks containing metadata. Overwriting makes data unrecoverable by replacing all data (user data as well as areas that are not accessible to the user) with patterns or non-sensitive data

Hardware Write Protect safeguards stored data by preventing modifications and deletions. This feature is enabled by putting a jumper on specific pins on the printed circuit board (PCB). Depending on the NAND flash product, the SSD will either deny write commands from the host or render the SSD in “Read Only” mode to thwart write access and data tampering
