As with standard ATA command, the software requirements and syntax of the vendor-
specific ATA commands the host issues to the Zeus SSD are issued to the ATA by 
loading the required registers in the command block with the supplied parameters, and 
then writing the command code to the register.

SimpleTech representative. Contact information is provided in “Contact and Ordering

Zeus SSDs offer optional destructive and non-destructive sanitization (purge) features. 
Non-destructive security erase removes the drive’s data, then overwrites (fills) each 
addressable block of memory with a predetermined pattern, as specified by the 
sanitization specification, such as DoD 5220.22M, to which the SSD complies.The 
destructive security erase feature removes the drive’s data, and then destroys the flash 
media—making the SSD totally unusable and data retrieval impossible. SimpleTech’s 
non-destructive and patent-pending destructive security erase algorithms monitor and 
confirm completion of the sanitization process.

Both security erase features support Low Power and Fast Erase options. The Low Power 
option accesses each addressable memory block sequentially to conserve power. The 
Fast Erase option accesses all addressable blocks simultaneously, forgoing power 
conservation for speed.
