Abstract: A method includes: preconditioning a reference solid-state drive (SSD) to a steady state by writing to physical media of the reference SSD; transferring metadata of the reference SSD to an application; storing the metadata of the reference SSD in a persistent storage; normalizing the metadata of the reference SSD to a target SSD; and applying the normalized metadata to the target SSD to precondition the target SSD to the steady state.

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).

Abstract: A method for notifying a host to manage background activities in a data storage device is disclosed. The method includes: receiving a query from a host operation system (OS); sending to the host OS, in response to the query, a list of background tasks to be performed in a data storage device; receiving a threshold value for one or more of the background tasks from the host OS; setting a timeout value associated with the threshold value; determining and notifying the timeout value to the host OS; determining that the threshold value is reached for a background task; and notifying the host OS that the SSD may perform the background task in the data storage device after the timeout value expires.
