SSD with powersafe
The secret to the high performance of the "powersafe" feature is the combination of sophisticated firmware and hardware features. Highly reliable tantalum capacitors that store energy while the SSD is in operation form the basis. In the event of a sudden power outage, the stored charge is used to safely write both dynamic data and data in the DRAM cache to the NAND flash array. Intelligent power management within the firmware ensures that the power supply disconnects from the host upon reaching a critical threshold and connects to the regulated voltage of the capacitors instead. This provides the SSD with sufficient power to safely execute write commands and flush cached data.
