Abstract
In a method for dynamic wear-levelling and load redirection in a solid-state drive (SSD) including one or more blocks, the method including: receiving, by a controller, a request to write data; calculating, by the controller, a vulnerability factor of the one or more blocks; selecting, by the controller, a target block from the one or more blocks to receive the request to write data; determining, by the controller, a status of the target block based on the vulnerability factor of the target block; writing, by the controller, the data to the target block based on the status of the target block; and updating, by the controller, a mapping table based on the data written to the target block.
