I am following this thread for quite some time now and I wanted to say how grateful I am for so many people sharing their experiences. Now I want to share mine. It's nothing really new, but still data which can be used for future expectations.
About two months ago I decided to upgrade my MacBook Pro Mid 2014 with a nice Kingston KC1000 960GB SSD. So I bought the green adapter from Sintech, formatted the disk via ubuntu bootstick accordingly and installed everything. I set the hibernatemode to 3 and for the first couple days everything seemed to run smoothly. After that kernel panics occurred quite regularly. I already had kapton tape in use, so I did not really know what to do here.
I had ordered a second adapter before reading here. It's form kalea (link below). I wanted to try it out. Didn't fit too well, no changes. So much for that experience, back to the sintech, which seem to result in less issues.
I tried experimenting with some power settings. I switched between the individual hibernation modes and simply tried to figure out how they would affect the system. It did not really matter, had similar problems with all, kernel panics, boot failures (disk not recognized) and so on.
I had read in another forum that one fixed similar problems by setting the standbydelay to a high value, basically keeping the computer from going into standby. Tried that by entering the suggested 84000 as the value, still problems after a while so I changed it back.
I reinstalled everything once, including new tape.. I don't know what I hoped would happen but now I am pretty much clueless on what to do. I could simply go back to my old ssd but that's boring.
In the following I want to add the problems that I experienced ever since I changed the ssd:
- kernel panics, mostly within the first minutes after booting when to many tasks are executed at the same time. When it is in fact running, it runs good. Never had issues while working usual hours during my workdays. When it's running, it's running.
- kernel panics when after getting the notebook out of sleep mode.. guess that's an hibernation issue
- battery life suffered, but that's acceptable.
- I started shuting off my laptop at the end of my days, cause I figured it might help hibernation issues. Well now after booting I get one out of four responses:
- regular boot (yeah!)
- no start-up disk found (folder, with question mark inside..., after a couple reboots everything goes 'fine'. Kernel panics might occur during the reboots...)
- No system folder found (circle with a slash symbol... takes a little longer compared to the previous one)
- Battery dead.. (though the battery is at 100%. After attaching the charger for the booting process i can detach it and the battery runs 'fine'. I should add that my battery is currently at 527 cycles. But I never had any problems with it before and its only been 2 months, since I changed the ssd. I can't tell if there is a correlation here.)

This turned out way longer then I thought it would. Sorry for that. Though, it might be interesting for some of you, especially if you're having similar issues or think about upgrading. Maybe someone even has a solution for some of the issues?
Kalea Adapter (not advisable imho)
Attached is also a screenshot from a speedtest. Somehow it changes sometimes, I got it up to aprox 930 once but around 720 seems to be the average.
