A method, according to one embodiment, includes selecting, from a buffer, a combination of compressed logical pages of data to maximize an amount of used space in an error correction code container. The method also preferably includes processing the combination of compressed logical pages to generate error correction code data. Furthermore, the method may include writing the data corresponding to the combination of compressed logical pages and the associated error correction code data to a non-volatile random access memory. Other systems, methods, and computer program products are described in additional embodiments.
