M.2 storage

Might be interesting to see how this goes. 

M.2 storage, particularly on NVMe, basically bypasses SATA and the whole AHCI command set to put SSD directly on the PCIe bus - lower latency, less CPU overhead, less power, etc.

Have a Samsung 950 Pro due to go into a next HTPC build on Linux. Will be interesting to see what it sounds like (if there's anything different). Will be coming together over the following weeks (waiting on other parts and some motherboard mods).
