During our meeting today, we may make forward-looking statements.

Any statement that refers to expectations, projections, or other characterizations of future events or circumstances is a forward-looking statement, including those relating to industry trends, technology trends, and expectations for the advance of all-flash data center. Risks that may cause these forward-looking statements to be inaccurate include among others: industry and technology trends may not evolve as expected, the amount of data in the digital universe may not increase as expected, and more companies may not consider all-flash data centers as expected; or the other risks detailed from time-to-time in SanDisk Corporation’s and Western Digital Corporation’s Securities and Exchange Commission filings and reports, including, but not limited to, their respective quarterly reports on Form 10-Q for the most recently completed fiscal quarter.

This presentation contains statements from third parties. We undertake no obligation to update these forward-looking statements, which speak only as of the date hereof or the date of issuance by a third party, as applicable.

InfiniFlash™ System and DataCore Software: Expanding Business, Not Data Center Footprint, for eHealth

Source: https://www.sandisk.com/business/datacenter/resources/case-studies/compugroup-medical-grows-business-without-growing-the-data-center

CHALLENGEAs business grew, CompuGroup Medical needed the same low latency and extreme performance as their Fusion ioMemory™ application accelerators, but were out of PCIe slots.

SOLUTION InfiniFlash System DataCore Software

RESULT 20X improvement in data access speed 3X power and cooling cost savings Data center space savings – 1 PB of storage in a 6U footprint

Case Study “Very large disks pose a

potential risk. I believe that the all-flash data center will become an option for most companies over the next two years, but not only because the failure rate is so low. Moreover, the cost for power and cooling can be decreased significantly. InfiniFlash is something every company should consider.”

—Thomas Schend, Senior IT Systems Architect,

CompuGroup Medical

Case Study “We have a business that is

running around the clock and all our customers are probably dependent on us for their mission or their company. If we don’t deliver they won’t grow.”

InfiniFlash™ System and Cloudera Enterprise: Implementing Data Lake for Better Business Decisions

Source: https://www.sandisk.com/content/dam/sandisk-main/en_us/assets/resources/enterprise/case-studies/sandisk-big-data-group-deploys-infiniflash-cs.pdf

CHALLENGEThe MemTech Data Scientists needed high performance, massive capacity, easily scalable storage for combined structured, unstructured, and semi-structured data from disparate data silos across the company.

SOLUTION InfiniFlash System IF500 256TB Cloudera Enterprise

RESULT Ability to store billions of rows of data in the data lake Sub-second performance 50X cost reduction compared to traditional IT data solutions

Case Study “We picked InfiniFlash based on

requirements. We could have selected any hardware we wanted. InfiniFlash is very competitive with respect to pricing, storage, performance and analytics. When you are extracting intelligence from data you first need to combine these data—structured, unstructured, and semi-structured. This is the use case for which we have deployed InfiniFlash as a data lake. This is the power of InfiniFlash.”

The Third Platform* in Action

• Consolidation from 24 to 5 storage systems

• Traditional apps -> traditional SAN with minimal growth and no new apps

• New applications -> new hybrid Flash / HDD tiered storage for UFOB across 6 replicated data centers

• InfiniFlash™ System as the tier-1 storage layer
