► Why a new SSD? › Existing SSDs: focused on IOps and latency › ExaDrive®: the first “data center” SSD › Ultra high-capacity › Record-setting density › Lowest energy consumption › Longer lifespan and data retention › Targeting users with performance, scale, and OpEx challenges › Cloud providers › Big data › Digital content › Technical computing 4

► Why a “data center” SSD? › Tiered storage for cost optimization › NVMe SSDs target the performance tier @ ~$1.50/GB › A “data center” SSD targets the capacity tier at 50% lower cost/GB › Analogous to HDD era of 15K, 10K, 7.2K rpm drives targeting different use cases › Substantial TCO benefits › Up to 5:1 reduction in rack space per TB (raw) › Up to 4:1 reduction in power consumption per TB (raw) › Adding dedupe/compression improves gains to 15:1 and 12:1, respectively › Data standardization › Nearline HDDs not going away, so 3.5” form factor + SAS are here to stay › HDD + SSD in same enclosure maximizes space, simplifies planning 5

► Why a new SSD vendor? › Gone baby gone: acquisitions have limited choice › Pliant (SanDisk) › Anobit (Apple) › Smart Storage (SanDisk) › Link-A-Media (SK Hynix) › Fusion IO (SanDisk) › IDT (PMC/Microsemi) › STEC (WD) › Virident (WD) › SanDisk (WD) › DensBits (Broadcom) › SandForce (Seagate) › Tidal (Micron) › OCZ (Toshiba) › Shannon (Silicon Motion) › Only 4 enterprise SAS SSD vendors today › Samsung, Seagate/Micron, HGST, Toshiba › All are captive to single NAND supply, creating risk for buyers 6

► What’s the market opportunity? › Robust high-capacity HDD market › 40 million units per year currently, all SAS/SATA (IDC) › But areal density gains of HDDs have hit a wall › NVMe in focus, but SAS+SATA market is larger (IDC) 7

► Why ExaDrive? › Traditional SSD architecture is broken › Single monolithic ASIC › Too costly as capacity increases › Excessive power consumption › Patent-pending ExaDrive architecture › Distributed approach, not a monolithic ASIC › Ultra-low power microcontrollers handle ECC, flash management › Intelligent processor manages wear-leveling and capacity › Architecture supports 500 TB SSD by year 2020 8

► ExaDrive-powered SSDs › Viking Technology › Division of publicly-held Sanmina › Called UHC-Silo (ultra-high capacity) › Launched July 11, 2017 › 50 TB and 25 TB capacities › Smart Modular › Division of publicly-held SMART Global › Called Osmium › Launched August 4, 2017 › 50 TB and 25 TB capacities
