Abstract: The system receives, by a first controller, data to be written to a first storage device. The data may not be accompanied by a cyclic redundancy check (CRC) signature. The system calculates, by the first controller, a first error detection code based on the data, and writes the data and the first error detection code to the first storage device. The system calculates a second error detection code based on the written data. The system performs a first integrity check of the written data by determining whether the second error detection code matches the first error detection code. The system performs a second integrity check of the written data by: obtaining one or more additional error detection codes from one or more other storage devices, wherein an obtained error detection code is calculated by a controller of a corresponding storage device; and determining whether the first error detection code matches the one or more additional error detection codes.

Abstract: During operation, the system receives a chunk of data to be written to a non-volatile memory, wherein the chunk includes a plurality of sectors. The system assigns consecutive logical block addresses (LBAs) to the plurality of sectors. In response to determining that a first sector is associated with an existing stream for the chunk, the system appends the first sector to one or more other sectors stored in a first buffer associated with the existing stream.

The system writes the stored sectors from the first buffer to the non-volatile memory at a first physical page address. The system creates, in a data structure, a first entry which maps the LBAs of the written sectors to the first physical page address.
