    Solid State Drives (SSD)


    Components of SSD:
    A) Controller
    B) DRAM
    C) FLASH bank

    Each FLASH chip is part of a common virtual pool and its space is addressed by the built-in controller.
    The controller monitors:
    • Wear leveling
    • CRC
    • Bad block mapping

    The controller provides support for interfaces such as SATA, PATA, SAS or FC
