Apacer’s DataDefender™ combines both firmware and hardware mechanisms to ensure data integrity. Together, they allow more time for volatile data to be stored in the event of power loss.
Since SSDs are often deployed in demanding environments, power disruptions may occur unexpectedly and potentially cause catastrophic damages to the data in the drive. |

When an unexpected power failure occurs, the firmware protection mechanism of DataDefender™ technology is duly activated and cuts off its data transmission from the host. Once power supply is resumed, the protection mechanism will rebuild the mapping table to ensure the integrity of the firmware as well as the data already written into the NAND flash media. In addition to the firmware protection mechanism, to further safeguard the in-process data, Apacer’s CorePower circuit and tantalum capacitors provide a backup power source. This hardware approach can ensure data transmitted from the RAM cache to the flash storage remains uninterrupted in the event of a sudden power outage. |
