Abstract

In mobile market, the popularity of TLC-based flash storage is steadily growing due to its high capacity. In this paper, we study the relationship between TLC-based storage and log-structured file system in terms of lifetime of the storage device. We also propose a novel technique, called Segment Trimming, which helps to eliminate the unnecessary data migration inside TLC storage. Our experimental results clearly show that our technique reduces the unnecessary data migration by 83% on average, compared with the traditional approach.
