1. A method, comprising:
- in a bridge, receiving a power down command and in response converting the power down command to a data hardening command;
from the bridge, issuing the data hardening command to a solid state disk;
in response to the data hardening command, hardening data stored on the solid state disk, the hardening comprising writing data in volatile memory to non-volatile memory; and
wherein the data that is hardened comprises user data and protection data.

Abstract
A bridge receives a power down command and in response converts the power down command to a data hardening command. The bridge issues the data hardening command to a solid state disk. In response to the data hardening command, data stored on the solid state disk is hardened. The hardening comprises writing data in volatile memory to non-volatile memory. The data that is hardened comprises user data and protected data. The data hardening command optionally comprises one or more of a flush cache command, a sleep command, and a standby immediate command.
