Patent ID: 8301832

Claim:
A method for writing data to persistent storage, comprising: receiving a first request to write a first datum to persistent storage, wherein the persistent storage comprises a plurality of NAND dies; in response to the first request: identifying a first NAND die in which to write a first copy of the first datum; identifying a second NAND die in which to write a second copy of the first datum; generating a second request to write the first copy of the first datum to the first NAND die; generating a third request to write the second copy of the first datum to the second NAND die; waiting until the first NAND die and second NAND die not are busy; based on a determination that the first NAND die and the second NAND die are not busy: issuing the second request to the first NAND die; and issuing the third request to the second NAND die after the second request is complete.
