I'm sorry to hear that. I was pretty excited to upgrade to Runcore last December. The improved performance was thrilling, but the problem was just too annoying that I couldn't stand anymore. I sold mine after a month. I'm sticking with Apple factory SSD now and pretty happy for the stability.
Am I just lucky? Why am I not experiencing any problems with my Runcore SSD? Is this a certain percentage of Runcore SSDs?
