摘要： An instruction to read at least a portion of a superblock is received where the superblock is stored on at least a first solid state storage die. It is determined if adjusted threshold information, associated with the first solid state storage die and the superblock, is stored. If it is determined that adjusted threshold information is not stored, then an adjusted threshold is determined and a read is performed on the first solid state storage die using the determined adjusted threshold. If it is determined that adjusted threshold information is stored, then a read is performed on the first solid state storage die using the stored adjusted threshold information.
