Screen brightness set down around 3 out of the 16 block scale (low). Test starting w/ fully charged battery, continual stream from Netflix via Safari (constant video and wifi activity) plus loop of movie playing via VLC locally from SSD (constant video and read from SSD).Info collected below: Apple SSD / Intel 760p other than fit, both appeared to work just fine.short 'B' adapter fit much better without the pressure on the case.long 'C' adapter worked just fine, but I didn't like how the case was closing.MacBook Pro (Retina, 13-inch, Early 2015).Also appreciate any feedback / insight on this setup. I can't swear the numbers are accurate, but they should be a fair relative comparison between the two SSDs. The following are very *non-scientific* results. Just contributing my experience if it helps anybody else.

I settled on the Intel 760p hoping for lower power consumption and full user capacity (as opposed to giving up 32gb w/the Adata SX8200 480gb stick). Truth is, I would probably have preferred an Apple 512gb SSD and been happy with it if I could have found the right price and some faith that it wasn't already worn out. I wanted to expand capacity while keeping power consumption and heat as low as possible. I was happy enough with the Apple SSD performance, especially being limited to PCIe 2.x on my machine.

Thanks for all the help in this very informative thread.
