AB - In traditional flash memory-based storage devices, the processing speed of the flash memory chips exceeded the transfer speed of the host interface, limiting the storage device's performance to the I/O bandwidth of the interface. However, the situation fundamentally changed as storage device interface technology evolved from SATA and SAS to NVMe. The NVMe interface leverages the PCIe bus to provide tens of times more transfer bandwidth than its predecessors, significantly exceeding the processing speed of flash memory. Consequently, the performance bottleneck has shifted from the interface layer to the flash memory processing layer, demanding a new approach to storage device design. This paper proposes an architecture to address this issue. It organizes multiple flash memory chips operating independently within an SSD into logical groups and applies an internal RAID technique to each group, enabling parallel processing of high-bandwidth data. The proposed method not only maximizes system throughput by effectively utilizing the increased bandwidth but also provides robust recovery capabilities against bit errors, chip failures, and data loss during large-scale data processing through RAID's parity-based error correction. Consequently, this research presents an efficient storage system solution that simultaneously satisfies high performance and high reliability in next-generation high-speed interface environments.
