[Crypto Erase]
SQFlash Crypto Erase is a security function based on vendor command supporting
both ATA command and NVMe protocol.  When Crypto Erase is activated, it will 
trim logical to physical table, fill data in it, and then reset the AES key.  
With this Crypto Erase function, we can ensure original data in SSD inaccessible 
through the NAND flash.

[Military Erase] 
SQFlash Military Secure Erase is a series of security function based on vendor
command which can be triggered by sending ATA Command on SATA SSD. 
Please check Military Secure Erase Whitepaper for detail of each functions: 
AFSSI 5020, DoD 5220.22-M, USA NAVY NAVSO P-5239-26, NSA Manual 130-2, 
USA-ARMY 380-19, NISPOMUP Chap 8, Sect.8-501, NSA/CSS 9-12, AFSSI 8580. 

[SQErase tool] 
supports all SQFlash SSDs and provide Cyroto Erase and multiple Military erases 
enabled through UEFI and free from OS compatibility issue.

[Sanitize] 
SQFlash security drives support Sanitize command sets by default and supports
Block Erase, Crypto Scramble, Overwrite and other related commands. With 
internal AES encryption support, Crypto Scramble starts with resetting AES 
key. In this way, the existing data will be scrambled within 10ms and can no
longer be recovered.
Also, the erase flag is set when the erase function is triggered, which will 
ensure the entire erase process can be 100% completed. Even if there’s power 
outage, the erase operation will resume as soon as power is restored.

(Note) Crypto Scramble needs to be done with the TCG OPAL 2.0 setting enabled.

[Secure erase]
(SATA Command): SQFlash SATA SSDs support standard SATA command for secure 
erase function; when the SSD controller receive the secure erase command, the 
eraseprocess will reset all blocks and erase all of the user data in the SSD.
