In one embodiment, a solid state storage drive comprises a plurality of flash memory devices configured to store a plurality of data clusters having a predefined data cluster size, and configured to store a first part of a first data cluster of the plurality of data clusters on a first page of flash memory and a second part of the first data cluster on a second page of flash memory, a partial buffer completion bitmap stored in a memory, wherein each bit in the partial buffer completion bitmap corresponds to a location in a buffer configured to receive data clusters read from the plurality of flash memory devices, and a controller configured to cause a page of data to be read from one of the plurality of flash memory devices, the page of data including either the first part of the first data cluster or the second part of the first data cluster, the controller including a queue buffer manager configured to change the status of a bit in the partial buffer completion bitmap when either the first part of the first data cluster or the second part of the first data cluster has been read from either the first page or the second page of flash memory and stored in the buffer. In one embodiment, the plurality of flash memory devices is further configured to store a first part of a second data cluster on the second page of flash memory and a second part of the second data cluster on a third page of flash memory.
