1. A method comprising: at a data storage device that includes a controller and a memory having single level cells storing first data associated with a first write command from an accessing device and associated with information from the accessing device indicating whether the first data is compressible, the first write command corresponding to a first context identifiable with a first context identifier included with the first write command, and having multilevel cells, performing: in response to a second write command from the accessing device, the second write command corresponding to second data and a second context identifiable with a second context identifier included with the second write command, determining whether the first context identifier of the first context matches the second identifier of the second context; if the first context identifier of the first context is determined to match the second context identifier of the second context, forming a group of data including the first data and the second data, the first context identifier assigned by the accessing device to indicate a first operational context associated with the first data within the accessing device, the second context identifier assigned by the accessing device to indicate a second operational context associated with the second data within the accessing device; and writing compressed data to a portion of the multilevel cells, the compressed data corresponding to a compression group of data and including at least one of the first data or the second data.
