Abstract:
A data storage device includes a controller coupled to multiple groups of data storage dies, such as a meta-meta-die. The controller is configured to write data to a first meta-block if a storage size associated with a first group of data storage dies associated with a first priority is greater than or equal to a threshold storage size. The first meta-block includes a respective block of each data storage die of the first group. The controller is further configured to write the data to a second meta-block if the storage size associated with the first group is less than the threshold storage size. The second meta-block includes a respective block of each data storage die of the first group and further includes a respective block of each data storage die of the second group. Each data storage die of the second group is associated with a second priority.
