Enhanced Power Loss Data Protection Enhanced Power Loss Data Protection prepares the SSD for unexpected system power loss by minimizing data in transition in temporary buffers, and uses on-board power-loss protection capacitance to provide enough energy for the SSD firmware to move data from the transfer buffer and other temporary buffers to the NAND, thus protecting system and user data. Hardware Encryption Hardware encryption is data encryption done at the drive level. This is used to ensure that the data stored on the drive is secured from unwanted intrusion. End-to-End Data Protection End-to-End Data Protection ensures integrity of stored data from the computer to the SSD and back.
