title = "Double hot/cold clustering for solid state drives",
abstract = "Solid State Drives (SSDs) which connect NAND-flash memory in parallel is going to replace Hard Disk Drives (HDDs). The physical trait of SSD is different from HDD and it uses Flash Translation Layer (FTL) to emulate HDD. Garbage Collection is the process of making an available sphere in SSD which has no function of an over-write. In the case of general policy of FTL, both of valid and invalid pages are randomly mixed, but if it could be separated, an effect of Garbage Collection can be improved. This paper presents a double hot/cold clustering scheme that separates the frequently overwritten region from the opposite. The performance evaluation result shows that the improvement is between 44.3\% in maximum and 3.9\% in minimum.",
