Enterprise disk sales off 13 percent.
Chris must be feeling a need to defend the drive vendors after the huge drop in enterprise disk demand this last quarter. 15K RPM drives are dead already and 10K seems destined for the same fate perhaps by the end of this year, though we'll always find people with nostalgic desires to use spinning rust. Violin is essentially right for primary tier storage!
That leaves the thorny question of what happens to the bulk storage tier, The "media evolution" comment above is close to the mark...economics will decide, and if there is a sure profit, the market will fund the foundries. With prices closing fast, the economics start to become compelling even before price parity is reached..
But will we need Chris' trillions. Data compression and deduplication will reduce space demand by as much as 5x. And, once 3D NAND gets out of the lab properly, the incremental cost to add 2 or 4x the layer count will be small. New error correction will move the sweet spot to TLC.
1 Trillion now looks like $40 Billion and possibly less! That's not much given market size.
