NezSez writes regarding an article in extremetech:

"SATA Express is SATA and PCIe over cables (preserving backwards compatibility) and NVMe is the next improvement of AHCI with much lower latencies by using the PCIe bus/lanes. Both have been developed to improve access to SSD's which have their own processors on-board and can communicate quicker than mechanical drives. The specifications look good (up to 4 times faster and can scale with improvements of PCIe) but analysts suspect it will only be adopted for small form factors.

    Doubtless he was, but you lose flexibility that way and only gain a tiny impedance advantage. I can't imagine that has a significant impact on speed.

    I wasn't thinking so much about impedance as the drastic reduction in the conductor length (millimeters instead of meters) reducing signal noise.
