Abstract
Disclosed herein are several methods and systems for handling atomic write commands that reach scattered address ranges. One embodiment includes a method of performing an operation in a data storage device, the method comprising: receiving an atomic write command; obtaining a plurality of ranges of logical addresses affected by the atomic write command; for each of the plurality of affected ranges, assigning metadata information to track completion of a write operation performed at that range; performing the write operations in the ranges of logical addresses; updating the metadata information upon completion of the write operations in the ranges; and deferring an update to a translation map of the data storage device until the metadata information has been updated.
