Abstract: A system and method for managing garbage collection in Solid State Drives (SSDs) (120-1, 120-2, 120-3, 120-4, 120-5) in a Redundant Array of Independent Disks (RAID) configuration, using a RAID controller (115) is described. A control logic (505) can control read and write requests (805, 810) for the SSDs (120-1, 120-2, 120-3, 120-4, 120-5) in the RAID configuration. A selection logic (515) can select an SSD for garbage collection. Setup logic (520) can instruct the selected SSD to enter a garbage collection setup phase (920). An execute logic (525) can instruct the selected SSD to enter and exit the garbage collection execute phase (925).
