    SAN normally provide cache to ease it, and SAN is always random io pattern.

    Are you saying that a SAN won't stream to multiple contiguous sectors on disk? If so, I find that very difficult to believe. It would spend most of the time thrashing the heads instead of writing.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
