Abstract
In a method for data placement in a storage device including one or more blocks and a controller, the method including: receiving, by the controller of the storage device, a request to write data; determining, by the controller, a data status of the data; calculating, by the controller, one or more vulnerability factors of the one or more blocks; determining, by the controller, one or more block statuses of the one or more blocks based on the one or more vulnerability factors; selecting, by the controller, a target block from the one or more blocks based on the data status and the one or more block statuses; and writing, by the controller, the data to the target block.
