For SATA III, we top out at about 550MB/s
With modern flash controllers and NAND, they can offer more than 550MB/s, (many are offering upwards of 700MB/s+ (using the same controller and flash from the SATA model).
We may soon see board layouts change with possibly 2 SATA ports only, and then 3-4 m.2 slots, and then standard PCI express for higher performance SSD's.
