   1.                                                   We note your discussion
on page 38 regarding a $605 million charge for manufacturing
                                                        underutilization and
related charges and a write-down of certain Flash inventory to lower
                                                        of cost or market
value. Please tell us, and revise to clarify, what is meant by
                                                        "manufacturing
underutilization and related charges." In addition, where you discuss the
                                                        risks and uncertainties
with regard to your strategic relationships on page 16 and
                                                        seasonality and
cyclicality on page 18, revise to include a separate quantified discussion
                                                        of charges related to
inventory write-downs and manufacturing underutilization to add
                                                        context to such risks.

2.       We refer to your October 28, 2019 response letter where you indicated
your intent to
         include a quantified discussion of units sold, average selling prices
or other metrics to the
         extent relevant to further promote an understanding of your results of
operations. Given
         the significant impact that macroeconomic factors have had on your
recent operations,
         please revise to include a quantified discussion of units sold and
average selling prices for
         both your Flash and HDD products as provided in the Quarterly Facts
Sheets of your
         Earnings Presentation to provide further context to your results of
operations discussion,
         or explain why you do not believe this information is relevant to an
understanding of the
         significant declines in your revenue and profit margins. In addition,
where a material
         change is attributed to two or more factors, including any offsetting
factors, revise
         throughout your results of operations discussion to ensure you include
a quantified
         discussion of each factor and avoid using terms such as "primarily" or
"substantially
         all" in favor of specific quantification. Refer to Item 303(b) of
Regulation S-X.
Notes to Consolidated Financial Statements
Note 3. Business Segments, Geographic Information and Concentration of Risk,
page 66

3.       We note your segment results presentation includes a line item for
"Total gross profit for
         segments." Please revise to remove this total as it creates a non-GAAP
measure
         that should not be included in the financial statement footnotes.
Similar revisions should
         be made in your Form 10-Q filings. Refer to Item 10(e)(1)(ii)(C) of
Regulation S-K.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.

       Please contact Megan Akst at 202-551-3407 or Kathleen Collins at

any questions.
