1 How it works Reduces mechanical power dissipated in air shear Allows platters to be placed closer together enabling more capacity Air N O O N Disk Rotation Disk Rotation Disk Flutter Reduced Flutter Helium Thinner Platters TMR-Errors Less Motor Power ~23% Mechanical Savings AIR 5 Disks N Nitrogen O Oxygen Helium He 7 Disks 4 C cooler 49% reduction in Watts/TB 2014 HGST, A WESTERN DIGITAL COMPANY 1

2 Helium is Safe Helium is non-toxic Used by deep sea divers as a nitrogen substitute Helium and safety Less helium in each new HDD Platform product than in a birthday balloon Helium is light and hard to contain it will immediately rise to the top of the room and escape faster than oxygen or nitrogen 2014 HGST, A WESTERN DIGITAL COMPANY 2

3 Ultrastar He 6 Helium Drive Benefits & Characteristics 50% More Capacity Lower Power Similar Performance Cooler Operation Reduced disk Flutter and better TMR = More platters, Higher TPI Less drag = Lower motor power ~1.6W lower power (idle) Sealed HDD spins at 7200 RPM ~4 C lower drive case temperature Lower power = less cooling needed More Robust Quieter Same Form Factor Hermetically sealed HDD is cleaner across broader environments Less air resistance = less noise 0.9 Bels lower during idle More platters in traditional 1 form factor 2014 HGST, A WESTERN DIGITAL COMPANY 3

Individual TCO may vary Costs include TOR and aggregator costs & power into rack cost ; Server cost is the customer cost of a complete 2U-12 server without HDDs. TCO savings vary based on PUE, cost of power, server type/density 2014 HGST, A WESTERN DIGITAL COMPANY 6

8 Capacity & Trademark Statements One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) equals 1,000GB (one trillion bytes), and one petabyte (PB) equals 1,000TB (one quadrillion bytes) when referring to hard drive or solid state drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the drive, the computer s operating system, and other factors.
