Dual Power Loss Protection
Technology with the power to protect your data
Exascend’s Dual Power Loss Protection is an advanced technology that effectively mitigates the potentially catastrophic effects that sudden loss of power can cause to flash storage and their data.
When a flash storage device suddenly loses power, in-flight data and data not yet stored in the non-volatile NAND flash risk getting lost and completely irrecoverable. Even worse, the mapping table – where the storage device keeps track of where data is stored inside the NAND flash – is at risk of severe corruption, making the storage device inoperable upon return of power.
Our Dual Power Loss Protection technology addresses these threats with a two-prone approach that encompasses both hardware and firmware.
Exascend’s firmware power loss protection which makes it quick and easy for the flash storage device to rebuild the mapping table upon return of power, allowing the application to continue using the SSD as if nothing had happened.
Hardware power loss protection, meanwhile, leverages tantalum capacitors that holds enough extra power for the storage device to flush all remaining data to the non-volatile flash before being forced to turn off due to loss of power.
Combined, they offer a high level of defense against sudden power loss and the catastrophic effects it may otherwise cause.
