Just because it comes up every so often.

My reason for choosing SATA is that it runs cooler and doesn't use your PCIe lanes.
 
It depends on the software you use. I use software development and CAD programs and these make heavy use of storage for read/write and both small and large files (for example one CAD program can write a 250MB undo file per edit, frequently reads from 15GB+ of SqlLite symbol libraries etc).

The switch from good SATA SSDs (850 Pros) to NVMe SSDs (970 Pros) was a night and day difference, although with other software I saw much less difference.
 
I just really hope that seperate data and power cables for SSDs goes away. Really don't need this many cables for a <5w device.

These power cables are not restricted to just SSDs though. As an example, I've got a power cable supplying extra power to a USB card with 4 dedicated controllers.
