Understanding Sanitization Standards
NIST SP 800-88 Rev. 1
Ameriki (US) standard jo modern media (SSD, NVMe) ke liye overwrite ki jagah Purge commands recommend karta hai. NIST Clear reusable assets ke liye hai, jabki Purge high-security disposal ke liye.
- • Clear: Single pass overwrite
- • Purge: Secure Erase / Crypto Erase
DoD 5220.22-M
Department of Defense ka legacy standard jo character (0), complement (1), aur random binary patterns use karta hai. Aaj kal ye modern SSDs ke liye recommended nahi hai kyunki ye drive ki wear leveling aur life kam karta hai.
- • Standard: 3 Passes
- • ECE: 7 Passes
