It gave a lower than expected outlook for the fall as he expected Apple and rivals to slow the growth of traditional, spinning hard drives by 10 to 20 percent over the next several months or more. CEO John Coyne tried to reassure investors by asking them to look to the long term, where he saw regular hard drives still leading mass storage for the next 10 years.
