the tiny NVMe RAID enclosure will come, eventually, I am sure, Ray...it's too good an idea not to, and yeah, I also think powering it could be achieved by a small external battery...if a 5V USB port can power one, sometimes even two SSD's, then powering a two NVMe chip RAID 0 "array" should be possible as well, and wicked fast.
I finally got my iPhone clamp in, and reduced the construction on top of my PCC4K to a bare minimum...just a 1/4 20 to 1/20 coupler screw, and this $7.99 clamp, plus a couple of thin strips of velcro to tighten and hold it a little bit more securely, and I even attached my cold show to the clamp's 1/4 20 hole that was facing me, for whatever else I might think of next (like attaching my RODE Video Mic Pro), and *bingo*, a check mark next to my "figure out a neat way to attach my SSD on top of my PCC4K" to-do list item (at least for now).
this is what it looks like (phew, I had no idea how dusty it is here):
as a next DIY project I'd like to figure out the most direct way to power the camera with a small power bank via its 12V 2pin connector...I saw that solutions have already been posted that look like they might be suitable.
but more importantly, now that the SSD sits safely on top of the cam, I hope to find some time to take it on its first test shoot outside...since that's what all of this if for, after all.
