  • Abstract
    A novel management scheme for the write buffer in solid-state drives (SSDs) is presented. The proposed scheme exploits the future buffer reference pattern by using I/O commands information in native command queuing (NCQ) of SATA SSDs. Through the trace-driven simulations, it is shown that the proposed scheme improves the performance of the write buffer significantly in terms of several metrics including the hit ratio.
