Abstract
An SSD has a plurality of dies, with each die having a storage capacity. The storage capacity of each die is divided into a primary capacity and a spare capacity. A primary die has a maximum primary capacity, and a sum of the spare capacities of the remaining dies is greater than the maximum primary capacity. Data stored on the SSD is distributed among the primary capacities of the dies. When a failure of a first die is detected, data stored on the failed first die is migrated to the spare capacity of at least one of the remaining dies.
