Let me put it this way: The microcontroller in a high-end SSD is often the limiting component that bottlenecks performance.

So, since RAM is MUCH faster than flash memory... it stands to reason the hardware microcontroller in the i-RAM is the biggest bottleneck. RAM should perform leaps and bounds better... a modern, performance tweaked microcontroller on the drive/iRAM PCB should give it a huge boost alone, before adding SATA II improvements and faster, higher bandwidth lower power DDR2 RAM.
