Abstract
Embodiments of the invention include systems and methods for recovering the system status and maintaining drive coherency after an unexpected power loss. In particular, these systems and methods reduce overhead for maintaining drive coherency by providing for pre-allocation of groups of write addresses and recording the pre-allocated groups of addresses to the non-volatile memory. Write processes can write to the pre-allocated group of addresses while the next group of addresses are pre-allocated and recorded to non-volatile memory.
