2.4.4Vendor-Specific ATA Commands

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.

2.4.4.1Sanitize Erase/Fill

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.
