New Commodity- Data is the New Oil

Source: Seagate Market & Competitive Intelligence

"Just as the politics of oil shaped the 20th

century industrial economy, so the politics

of data will shape the 21st century digital

economy… data is the new oil, the vital

fuel of our digital economy,“ Andrew Keen, CNN, Jan 27, 2012

Driven by 2 major trends

• Big Data • gathered, e.g., by social networks, online

commerce, …

• used to analyze and shape consumer buying

trends, marketing strategies, medical trends,

financial services, social studies, …

• Cloud Computing • similar in concept to mainframe and client-

server computing of yore

• permanent accessibility from vast number of

smart mobile devices

Thousands of Petabytes

Exabyte growth is 40% per year…how to meet that

demand?

10/06/2012 CAISS 6

Areal Density Growth Trends

During the last 10 years the number of

drives shipped increased from 200

million to 600 million, this is a 3x

increase in shipped drives

During the same period, the average

capacity of the drive has increase from

17 GB to 565 GB, a 32.5x increase.

With the average number of heads per

drive increasing from 2.5 to 3.5, the

average areal density of the drives

increased by just over 23x (or about

35%/year) during the last ten years

Historically we have used areal

density growth and not more heads

and media or more drives to satisfy

Exabyte growth, but the existing PMR

technology is approaching its limits

10/06/2012 CAISS 7

Why can’t we just build more drives?

Assuming areal density does not increase and the number of

heads per drive remains fixed (in other words, just build more

drives) we would need to expand capacity at 40% per year.

Adding that kind of capacity would cost a company like

Seagate billions of dollars annually

But it would also mean that Dell, Google, Microsoft, etc., would

need to build a new data center every two years at a cost of

$300 million per data center. In addition, these companies

would have to maintain their data centers which means that

their ongoing cost of operations, e.g., power consumption,

would also be growing at 40% per year.

Facebook alone spent $606 million in 2011 on their data

centers.

These added costs will get passed on to consumers in the

form of higher costs

Economically, our customers need us to increase areal

density to keep costs for storage under control and that is

why we need HAMR (or any other technology that

allows us to continue AD growth)! !

A HAMR Drive

To the right is a photo of an actual HAMR drive.

You can tell it is a HAMR drive because it has

the laser warning sticker stuck on the front

Below is a picture of an integrated HAMR head

including the laser (not the same head used in

the drive)

to Wall Street analysts using a fully functional

HAMR drive on Sept. 21, 2012.

Conclusion

The customer base of the storage industry is rapidly changing, and

we need to change accordingly

We need capacity and areal density growth to keep up in an

economical way with the rapid growth of storage demand

We need HAMR (or any other technology that allows us to continue

AD growth)!

HAMR is for real in Seagate’s view is the next HDD technology

By building HAMR drives you gain unique insights into HAMR that

can not be foreseen by spin stands alone

Although read back is largely unaffected by HAMR, major portions of

the drive architecture need to be re-designed to accommodate HAMR
