Hi Guys, I bought a SSD KingSpec and had the same problem, after few days My Macbook Pro 2017 didn't boot, I tried so many things 'til I realized that the KingSpec is thicker than original, so the bottom cover put pressure on the SSD 'til it started to fail. The solution was not to close completly the bottom cover but putting all the screws, now it's working fine since then (a couple months). Hope this solution can help you guys
