Abstract: A flash file system and a data management method thereof are provided, the system including: a creation module, configured to divide a flash memory into a file system region and a flash buffer region; a marking module configured to mark written data as dirty data in a memory buffer when the data are written and an amount of the written data is less than or equal to a preset marking threshold; a synchronization module, configured to merge the dirty data in the memory buffer and write the same into the flash buffer region when data synchronization is required, and notify a backfilling module when the flash buffer region is full; and the backfilling module, configured to read the dirty data in the flash buffer region, write the dirty data into the file system region, and erase the flash buffer region.

Abstract: Disclosed are method and apparatus for predicting hard disk fault occurrence time of hard disk failure, and storage medium. The method includes steps of: screening a hard disk on the verge of failure from a plurality of hard disks according to state data acquired of hard disks; calculating variation quantity and discrete quantity of each piece of the state data of the hard disk on the verge of failure acquired over a first preset period of time, to obtain a first predicted data set; and inputting the first predicted data set into a first training model to obtain probability of occurrence of failure for the hard disk on the verge of failure over a future second preset period of time.
