Abstract: A method, a computer readable medium and a system for managing flash memory. The method may include receiving multiple data sectors from an interface; writing the multiple data sectors into a data buffer that is nonvolatile; creating a pointer in a data management structure that is stored in a metadata buffer that is nonvolatile, for each data sector corresponding to a storage location of the data sector in the data buffer; if a predefined condition is reached, merging data sectors stored in the data buffer with data sectors that are already stored in a sequential nonvolatile portion of the flash memory device, wherein the sequential nonvolatile portion differs from the data buffer.
