要約(英語): By 2020, all the data are expected to redouble every two years, which means 5 terabytes of data for every person on Earth. The difficulty of storing and fetching required data from data centers and servers will consequently increase. As a result, significant attention has been paid to the flash memory-based Solid State Drive (SSD) which made replacing the existing Hard Disk Drive (HDD), used as a storage unit across the world, very possible. Flash memory the basic unit of SSD, has many distinctive characteristics that lead to various challenges. Flash memory doesn’t support update in place method. A write operation can only be performed on an empty or erased unit which makes it more timeconsuming. Moreover, each storage unit has limited number of erase cycles. In this research, a new scheme called Performance and Reliability Awareness (PRA) proposed to increase the reliability and performance of SSDs.
