Abstract
Some data storage devices select blocks of memory from a free block pool and randomly allocate the blocks as primary and secondary blocks to redundantly store data in a write operation. However, some blocks, such as blocks on the edge of a plane, may not serve well as primary blocks. One example data storage device presented herein addresses this problem by allocating such blocks as secondary blocks instead of primary blocks.
