40 Zeus 2.5-Inch ATA Solid State Drive
Vendor-Specific ATA Commands
As with standard ATA commands, 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.

Sanitize Erase/Fill
Zeus SSDs offer optional destructive and non-destructive sanitization (purge) features. Non-
destructive security erase removes the data from the drive, 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 data,
and then destroys the flash media, making the SSD totally unusable and data retrieval impossible.
The 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.
