| ***''I just did this upgrade.''*** Sabrent Rocket 1TB 2242 NVMe paired to the same NFHK N-1708A adapter. I did not experience any significant issues. Of course, I read this entire stack of replies (''plus a LOAD of other threads and videos'') but it appears to be hit and miss for a lot of people. I seem to have hit square on with write @ 18k and read and 21k. This is a 3x write increase over the 128GB Apple SSD, so I'm very happy. I don't think I did anything unusual...? [br] | |

| + | What I did is not any different to you and to be honest, I think you have a dud SSD. It's either that or it's an OSX compatibility issue which are the only things I can think of. Here's what I did...[br] |
| [br] | |
| a. Obvious prep to get ready for the new SSD, backup etc etc[br] | |
| 1. Installed the SSD and left the bottom off just in case. Plugged everything back in.[br] | |
| 2. Booted the machine up and got the question mark folder. ''Uh oh... what did I do wrong?''[br] | |
| - | 3. Command R, reboot and the machine didn't recognize the drive. '' |
| + | 3. Command R, reboot and the machine didn't recognize the drive. ''$@$*... am I done?'' [br] |
| 4. Plugged it in, PRAM reset - audible chime difference. ''That's interesting...''[br] | |
| 5. Command R again, Disk Util - and the unit recognizes the drive!! ***''YES!''***[br] | |
| 6. Expand directories and Format + rename drive to GUID as per usual.[br] | |
| 7. Reboot again, PRAM reset again, SMC reset as well. Load Command R and get the screen where you can choose... ***''go to the spinning globe.''***[br] | |
| 8. Chose a fresh install for High Sierra and waited. ''If this works, I know I'm good to go.''[br] | |
| ''9.'' Sure enough, it loaded just fine and the drive was now registered and operational. [br] | |
| 10. Noticed some random warnings about this: | |
| - | |
| + | ***''MCA Error Report''*** |
| ''CPU Machine Check Architecture Error Dump (CPU: Intel(R) Core(TM) i5-7360U CPU @ 2.30GHz, CPUID: 0x806E9)'' | |
| ''CATERR detected! No MCA data found.''[br] | |
| [br] | |
| 11. Slight panic but the computer isn't acting strange at all - everything seems totaly fine - so I'm ignoring it. [br] | |
| 12. Upgrade from High Sierra to Catalina through a target disk via USB.[br] | |
| 13. Trouble shoot some bugs and Enable TRIMFORCE just in case as I don't want Apple thinking I'm doing anything dodgy. ''It ***is*** my machine after all, isn't it?''[br] | |
| 14. Check the battery drain and write/read speeds - everything seems really good so far! Got 9 hours from my first charge and seems stable at ***''17 to 19k write 20 to 21k read. BUT... I am noticing some fade/dropoff/wilt/leak of the write speed. It will hit 19k for a few cycles on Blackmagic and then drop through the floor to 1000 or under... and then shoot back up again while read stay consistently at < 20k ... I wonder why that is???''***[br] | |
| 15. Backed up from my Catalina file and all is well! I have not really had a single issue I couldn't fix so I would suggest it may be a hardware fault OR it is something to do with the firmware you're trying to upgrade from perhaps? [br] | |
| [br] | |
| Try doing the PRAM reset first as soon as you want to start it up, make sure it is plugged in and then do it a couple of times before going Command R and looking for Dick Util so you can go from there. Once you hit Disk Util you are basically 90% of the way finished and it's a bit tedious to that point but from my perspective well worth it. |
