This is interesting if EXTREMELY talky:
I expect PCIe is where motherboards will be going for both storage and other (like dedicated graphics) types of addons. The bandwidth is far higher than even SATA/6. The beauty of being able to push I/O data through at these crazy speeds is we're starting to finally get rid of the gap between the CPU pipe and the storage in speed terms, which usually slowed the system down due to "starvation" happening.
