Anyone know where I can buy the internal Samsung PCIe SSD for a nMP in the UK? Obviously I can take it to Apple and get them to do this, but I can get back to normality quicker if I can get it somewhere else. My nMP started throwing kernel panics a few weeks ago and it got worse and worse to the point where it would just freeze a few minutes after logging in. It does not even bother throwing a kernel panic anymore. I cannot get into the recovery partition on the drive. It starts to boot and then freezes. If I use internet recovery, disk utility does not see the internal storage. Or it sees it, but if you do anything like diskutil list or gpt show then it works the first time and shows the internal storage, but then it magically disappears and cannot be accessed via the command line, or disk utility. I also get blue screens in Windows 10 every now and then. Everything works perfectly fine if I boot from an external SSD clone, except that I cannot see the internal storage. The internal storage does still show up if I hold alt when booting up though. The internal storage is also accessible via target disk mode from another Mac, so I nuked it and then cloned a fresh copy of OS X into it and created a new recovery partition, but the same issues persist as before.
