This seems to offer a lot of benefits without much drawback. Can someone clarify why this isn't almost always used? Would heat/power consumption be the issue?

3D stacking is emerging technology that you'll likely see used more and more often for high performance systems in the coming years.

I was thinking that why DRAM can't adopt the architecture like disk. 8 plates construct a cylinder, then one controller can control all the plates. DRAM can also let 8 banks be a group, and have 8 groups, as data request a always larger than 64*8 bits, I suppose it will have a big improvement.

@black I feel like the architecture of hard disks (SATA) is more like a compromise than a feature since the plates have to spin and pin has to locate data... and a cylinder would occupy more spaces than a chip. And now days Solid State Disks are more and more popular since they are faster and smaller, the architecture of disks is more and more like a DRAM :)
