Abstract
Recently, many researchers have focused on the log-structured file system because its layout helps to enhance the performance of the consumer electronics (CE) devices that employ NAND flash storages as their main storage. In this paper, we present a novel hot-cold separation scheme that dynamically identifies the temperatures of blocks in the file system with a hint from the page cache. Our experimental results clearly show that our scheme reduces the number of copy operations by up to 6.1 times compared with the F2FS. © 2017 IEEE.
