An embodiment of the present invention includes a method of implementing the logical grouping of memory system sectors in a non-volatile memory system in order to increase the operational speed of the memory system, the method comprising allocating sets of contiguous logical sectors containing file data from a host system into logical groups; ensuring that a logical group includes fewer sectors than there are sector locations in a memory block in the non-volatile memory; aligning the logical groups with the clusters into which the host system organizes sectors containing file data; writing sectors within a logical group to contiguous locations within the non-volatile memory; organizing the on-volatile memory such that the corresponding sector in each logical group is written to a corresponding array within the memory; the arrangement being such that the reading then writing of a sector of a cluster to relocate it to a different location in the non-volatile memory takes place within the same array, thereby allowing concurrent relocation of all sectors in a logical group.
