Forward Looking Statement

This presentation contains forward-looking statements that involve risks and uncertainties, including, but not limited to, the development and adoption of a new storage architecture and the potential introduction of products based on this architecture. Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved, if at all. Forward-looking statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements.

Additional key risks and uncertainties include the impact of continued uncertainty and volatility in global economic conditions; actions by competitors, business conditions and growth in the various hard drive segments. More information about the other risks and uncertainties that could affect our business are listed in our filings with the Securities and Exchange Commission (the “SEC”) and available on the SEC’s website at www.sec.gov, including our Quarterly Report on Form 10-Q filed with the SEC on May 5, 2014, to which your attention is directed. We do not undertake any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as otherwise required by law.

Active is #1 requirement in storage

0 IOPs

High IOPs

High-value historical data

• The value of dataWhen data is more readily accessible, it’s value increases

• Traditional “tiers” of data are compacting

High-speed, low latency

Low-speed, higher latency

Archive must be accessible

• Affordable disk media solutions offer ideal price/performance

Spinning disk is NOT dead

Software-defined storage

Other HGST code projects

• With expertise from HGST Research, opportunities for contribution include:

- Erasure coding approach that recovers from 2 failures

- First parity as standard row parity for efficiency

- Leveraging XOR functions to complement software-defined solutions

- Optimized bandwidth and access ratios for recovery

»Resulting in 50% reduction in data read when recovering from one erasure

- Other optimizations to Ceph

Think HGST for efficient Ceph clusters

• HGST is happy to participate in the Ceph community

Patch contributions today, looking to contribute more

Exploration of optimizing Ceph services as close to the drive media as possible

Discussing solutions for software-defined scale-out storage in the data center

• HGST Ultrastar He6 hard drives great for Ceph today

49% lower power / TB, both 50% additional capacity and 38% lower weight / TB

• HGST Ultrastar He8 TB hard drives shipping Now!!!
