What is the main function of the SATA DOM in the Topaz 410?

The main function of the SATA DOM (Disk on Module) in the Topaz 410 is to provide data storage. SATA DOMs are specialized storage devices that connect directly to a SATA interface, offering an efficient solution for storing data required by the system. Within the context of the Topaz 410, the SATA DOM serves as the primary means of storing operational data, applications, and system files necessary for the device's functionality. This solid-state storage solution enhances the reliability and speed of data access, which is crucial for processing transactions and managing operations in a payment terminal like the Topaz 410. While power supply, communication interfaces, and software execution are essential components of the device, they do not directly relate to the primary role of the SATA DOM, which is focused specifically on data storage capabilities.
