I sincerely doubt iSupply's optimistic views. After the current never-ending FAKE HDD crisis, developments will happen very slow and prices will remain much higher than they've ever been for the rest of the decade.

Unless SSDs pose a real capacity threat (and that won't happen anytime soon) HDD industry is going to move very slow.

19% annual growth isn't optimistic. It's depressing.

19% annual growth in product capacity or in any line of business is remarkable. Period

If 19% annual growth is remarkable, then what is 100% growth per year? HDD capacities used to grow that fast. For information technologies it's a norm to grow twice every two years. 19% annually is super slow.

Unless HDD makers improve reliability, increased density is of little value. Same applies to SSDs for compatibility and reliability.

FWIW, in a mature market as HDDs are in, 19% annual growth would be outstanding. SSDs will see high sales volume growth increases year-over-year as they are just being introduced to mainstream consumers but are still too expensive for std. hardware in many PC applications.

So doubling density (tb/in^2) is equivalent to squaring capacity (from say a 4TB drive to a 16TB drive)???

No. Terabytes per square inch is just that... per square inch. Since platter surface size is basically a fixed area per side, doubling the density doubles the storage for a drive with the same number of platters using the same number of sides.

If that is true, then a 20% increase in desnity (x 2 years) would project to above/below normal (in regards to Moore's Law)? Not so good at the math, but I would reckon about on track.
