Embodiments of the invention are directed to systems and methods for detecting sequential write threads in non-volatile storage media. The embodiments described herein detect write commands directed to a range of logical addresses corresponding to a write thread. Upon detection of a write command directed to a write thread, the write command is assigned a physical write address associated with the write thread. Identification of write threads can be implemented with a hardware component which performs comparison operations between the write command address range and the write thread address range.
