Systems, methods and/or devices are used to enable a stale data mechanism. In one aspect, the method includes (1) receiving a write command specifying a logical address to which to write, (2) determining whether a stale flag corresponding to the logical address is set, (3) in accordance with a determination that the stale flag is not set, setting the stale flag and releasing the write command to be processed, and (4) in accordance with a determination that the stale flag is set, detecting an overlap, wherein the overlap indicates two or more outstanding write commands are operating on the same memory space.

Data storage system with stale data mechanism and method of operation thereof

A storage control system and method of operation thereof includes: a control unit for initiating a hardening process beginning at a power-down signal; a counter module, coupled to the control unit for tracking a recorded time beginning at the power-down signal; a completion module, coupled to the counter module, for generating a work-complete entry in memory devices at a conclusion of the hardening process; and a calculation module, coupled to the completion module, for calculating a power down margin by determining the recorded time between the work-complete entry and a complete power loss of a hold-up power.
