    I would not expect any issues as long as the drives are the same size,
    you should be fine.
    And in reality, 15K drives only give decent performance gains in certain
    workloads (mainly
    small random I/O). Your mileage may vary, but that's what I've seen.

    Subject: 144GB drives mixing 10k/15k in same aggregate

    it appears netapp is only shipping 15k 144gb drives now. all of our
    existing aggregates are 10K drives. we need to expand an existing
    aggregate. other than not getting the full benefit of an all 15K rpm
    aggregate will this cause any issues. we are already happy with the
    performance of the 10k drives and im pretty sure this wont have any
    affect but just checking.

    of course it would be much more noticeable if we went from 15k to 10k.

    thanks
