    Abstract: The invention relates to systems for storing data on disk drives and makes it possible to accelerate the redistribution of data. At least one physical disk drive is added to a disk array. The stripes of the data disk array are divided into groups, wherein the number of stripes from the original configuration of the array is selected such that, when data are migrated, they occupy an integer number of stripes. The data from each group of stripes are migrated successively to a pre-reserved data writing area, and then the data from this group of stripes is written to stripes of a new configuration of the disk array. When the size of a free area becomes greater than the size of a group of stripes for migration, the data from each group of stripes of the original disk array are migrated and written directly to the stripes of the new configuration.
