Abstract
An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions that write data having mixed deletion characteristics sequentially to a plurality of data entries of a first physical erase block (PEB) in intermediate storage. The data having the mixed deletion characteristics includes first data having a first deletion characteristic. The processor has programmed instructions that maintain metadata in a plurality of metadata entries in a log. The metadata corresponds to the data having the mixed deletion characteristics. The processor has programmed instructions that identify, using the log, the first data having the first deletion characteristic and evacuate the first data having the first deletion characteristic to a second PEB in main memory.
