You should not have a problem with DFSORT if you disable cache fast write in your contoller. Even if the DFSORT default is CFW, the controller will simply ignore the CFW flag and treat it as a normal write. Generally, I have not seen a significant perfomrance impact to DFSORT when CFW is turned off. This is mainly due to the larger NVS sizes and high speed interfaces of today's storage technology.
