    From the hdparm manpage:
    -T [...]
    This displays the speed of reading directly from
    the Linux buffer cache without disk access. This
    measurement is essentially an indication of the
    throughput of the processor, cache, and memory of
    the system under test. [...]

    So 33MB/s is quite realistic, but in no way characteristic for your HD.
