Abstract

See full text

Provided are a power failure protection method and solid state drive (SSD). The SSD comprises: a power-failure detection device, for monitoring in real time whether the power supply is abnormal; a power-failure protection device performs a power-failure protection operation when the power supply is monitored to be abnormal: breaking a connection with a host system bus, an SSD internal clock breaking from a system bus clock and writing data in the SSD cache into a storage unit of the SSD by using the SSD internal clock. The technical solution ensures completion of the data protection operations by utilizing a remaining capacity, thus ensuring data integrity.
