In one implementation, a method includes maintaining a list of available allocation units across a plurality of flash devices of a flash storage system, wherein the flash devices map erase blocks as directly addressable storage, and wherein erase blocks are categorized by the flash storage system as available for use, in use, or unusable, and wherein at least a portion of an erase block can be assigned as an allocation unit. The method further includes receiving data from a plurality of sources, wherein the data is associated with processing a dataset, the dataset comprising multiple file systems and associated metadata. The method further includes determining a plurality of subsets of the data such that each subset is capable of being written in parallel with the remaining subsets, mapping each subset of the plurality of subsets to an available allocation unit, and writing the plurality of subsets in parallel.
