The ‘Set Configuration’ and ‘Save Configuration’ buttons are only available in the synchronous version of WinSSD test utility that is included in the SeaMAC software suite.
Clicking the ‘Set Configuration’ button will send the configuration currently defined in this window to the SeaMAC driver. If successful, it will cause the driver to be configured as defined. The configuration settings will revert to the previous default settings when you close WinSSD.
Clicking the ‘Save Configuration’ will send the configuration currently defined in this window to the SeaMAC driver (same as the ‘Set Configuration’ button). If successful, it will also tell the driver to save the current settings as the new default configuration. The new settings will be available whenever the port is opened, even after a reboot.
