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.

    I don't think the days of spinning disks are anywhere near over. The cost per GB and size per unit is still a hell of a lot better than solid state can manage yet.

    ...although having said that, I realised that I'm automatically in my head comparing 7k SATA and SSD, not 10k SAS and SSD. So I must qualify my statement and say that the only defense SAS will shortly have is it's legacy support in everyone's racks.
