Abstract
A data writing method of a flash disk array is provided. The data writing method includes steps of: obtaining a first data quantity; receiving intermediate data to be written into the flash disk array; comparing a second data quantity of the intermediate data with the first data quantity; and writing the intermediate data into the flash disk array when the second data quantity is not less than the first data quantity. At most one data block is allocated from each of flash drives. Some of the allocated data blocks are written with the intermediate data, while others of the allocated data blocks are not written with the intermediate data and provided as reserved blocks. The number of the reserved blocks has at least two selectable values dependent on residual lives of the flash drives.
