Question · Q2 2026
Ananda Baruah asked if Western Digital anticipates an acceleration in its cost per exabyte reduction beyond the current 10% year-over-year, given the increasing mix of UltraSMR and the upcoming HAMR technology, which is expected to be margin-neutral to accretive. He also inquired about the maximum areal density achievable with CMR and UltraSMR before HAMR becomes fully operational.
Answer
CFO Kris Sennesael confirmed the current ~10% cost per terabyte reduction and stated that continued innovation, higher capacity drives, and increased UltraSMR adoption will drive further cost reductions, potentially accelerating if roadmaps advance. CEO Irving Tan deferred the question about maximum areal density for CMR and UltraSMR before HAMR to the upcoming Innovation Day.
