single-lane PCI-e is still only gigabit, phil, and SATA-II is 3.0
gb/s. so it still really doesn't cut the mustard. you'd need a 4x
PCI-e to meet the SATA-II specification, and that would mean you'd
have a) lots of pins b) lots of heat. c) an expensive system.
you really really want a SoC that already has the required interfaces
built-in. if they're built-in, you aren't driving some wires at mad
speeds and wasting heat to do it.
