QLRU: NCQ‐aware write buffer management algorithm for SSDs

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.
