Abstract
A method for writing data to persistent storage. The method includes receiving a first request to write a first datum to persistent storage including NAND dies, identifying a first NAND die in which to write a first copy of the first datum and a second NAND die in which to write a second copy, generating a second request to write the first copy of the first datum to the first NAND die and a third request to write the second copy to the second NAND die, and 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.
