dc.description.abstractNowadays, significant attention has been paid to the flash memory-based Solid State Disk (SSD). Different from traditional disks, SSD uses semiconductor chips for storing the data. This structure enjoys original technical characteristics including low power consumption, shock resistance and high performance in random access. Owing to these features, many devices are using flash memory as a basic storage component, such as mp3, smartphones, and tablet devices. However, the flash memory, basic unit of SSD, has many distinctive characteristics, which lead to multifarious challenges for example, writing data (storing data) is only allowed on empty storage unit (block), which makes it more time-consuming. Moreover, each block has limited number of erase cycles. In this research, two novel schemes are proposed. The first one is called Clustering-based Garbage Collection (CGC) aimed at increasing the reliability and performance of SSD. Whereas, the second one is called Three-tier Flash Memory-based Storage Management scheme (TM) for hybrid SSD (i.e. SSD consisting of different types of flash memory) in order to increase the performance, reliability, density, and reduce power consumption. The eligibility of the CGC and TM schemes are proven by using DiskSim simulator. The results reveal that the proposed schemes are very competitive to state-of-the-art schemes in various real-workloads. In terms of reliability, the percentage of enhancement is in the favor of CGC over the other schemes amounts to 86.56 %. In terms of performance, the percentage of enhancement is in the favor of TM over the other schemes amounts to 185.55 % .en_US
