SafeDATA technology combines unique power loss detection and hold-up circuitries with an advanced controller firmware algorithm to flush in-flight data from volatile cache to NAND Flash memory in order to safeguard data against corruption and/or loss during the sudden power loss.
When power failures occur during system operations, drives can be corrupted and data is damaged. This results in downtime as drives must be reformatted, operating systems have to be reinstalled, and products could be returned for RMA.
Power loss protection technology is one of the most important value-added features and makes the biggest difference within the embedded SSDs. Truly RUGGED SSDs are equipped with both hardware and firmware architecture levels that could withstand aggressive power cycling.
How Does It Work?
SMART’s SafeDATA technology ensures stable power supply for an extended period of time right after detecting unexpected power drop. Power Management IC plays an important role in sharing sufficient electricity with all the devices on board to make sure data is securely processed and stored from the DRAM cache to the NAND.
The average processing time from backup power relay to data storage completion usually takes about 40ms-60ms depending on computing complexity or size. SMART’s SafeDATA technology offers 80ms-120ms longer buffering time to strengthen data integrity in the event of power failure.
