Abstract

The invention discloses a method and a device for protecting power failure data of a solid state disk. The method comprises the steps of: detecting power failure of the solid state disk, and switching a working power supply to a preset energy storing device to provide power for the solid state disk; in a period for providing power for the solid state disk by the energy storing device, storing data being read and writted by the solid state disk to a disk; and detecting the working power supply and restoring power, and switching into the working power supply from the energy storing device to provide the power for the solid state disk. By the processing, when the solid state disk is in abnormal power failure, the data being read and written by the solid state disk can not be lost.

Description

technical field [0001] The invention relates to the field of solid-state hard disks, in particular to a method and device for protecting solid-state hard disk power-off data. Background technique [0002] In related technologies, the power-failure protection technology means that when the normal power supply is powered off, the backup power supply is quickly used to supply power to the storage device, so as to ensure that the information of the storage device will not be lost within a period of time. Switch to mains power supply. [0003] For hard disks, the data that needs power-down protection is often written data. After the main power supply is powered off, the system that requires high reliability of data needs to use an uninterruptible power supply (UPS for short) to continue to provide power for the system. powered by. For example, after the system is powered off, a battery backup unit (Back Battery Unit, BBU for short) supplies power to the memory, the memory contr...
