Multi-tiered storage device system and method thereof

A system for controlling a multi-tiered storage device (MTSD), the system comprising:

• a processing unit (PU);
• an input/output (I/O) interface communicatively coupled to the MTSD, the MTSD comprises a first storage comprising one or more storage devices, and a second storage comprising one or more storage devices, each storage device of the first storage has a higher write endurance than each storage device of the second storage;
• and
• a memory communicatively coupled to the PU, the memory storing instructions that when executed by the PU configure the system to:
• receive a block of data;
• write the received block of data to a first storage device of the first storage;
• assign a timestamp respective of the received block of data;
• and
• write the received block of data to a second storage device of the second storage, upon determination that a time elapsed since the timestamp is above a first threshold value.

A system comprising:

• a controller;
• and
• a memory that stores information arranging storage devices in a multi-tiered storage device (MTSD) into at least two groups including a first group of storage devices and a second group of storage devices, the storage devices in the first group of storage devices have a write endurance that is higher than a write endurance of the storage devices of the second group of storage devices,
• wherein in response to the write endurance of a first storage device of the first group of storage devices falling below a threshold, the controller re-assigns the first storage device to the second group of storage devices.
