Back in the mid-70s I was a software developer on mini-computers, which meant writing in assembly language—just pointing out that I’m ancient so go easy on me, or don’t. 😉
Back in May 2020, my mid-2014, 15”, 2.5GHz, 512G SSD booted into the black screen with a folder containing a question mark. Nothing I could do would revive it and I found your excellent thread.
I read the first couple pages and bought a 512G Samsung 970 Pro SSD and a Sensico M.2 adapter rather than Sintech (impatient with 2 WK delivery because I was down).
Through dumb luck more than skill, everything worked the first time. I was able to perform an internet install of Catalina (already on that rev before it failed) and got a time machine backup to work. Since then I’ve installed every Catalina update without issue.
My MBP is at Apple Service getting some free work done replacing the delaminating screen and I learned the hard way that I had to remove the non-OEM SSD before they would repair it—back and forth twice to them.
The three problems with nvme SSDs: no Bootcamp, Hibernate hang-up and high power consumption have all bit me but I installed Parallels, used the Terminal command to stop hibernation and live with about 1/2 to 2/3 battery life, which isn’t too bad since I put in a new battery in March because the old one had swollen causing the touch pad to barely function.
While it’s being repaired I’m thinking of getting a used Apple SSD so I have some flexibility. I have a couple questions and would appreciate your collective wisdom.
1. Since my mid-2014 MBP has PCIe 2.0, will it pickup any speed with an SSUBX SSD?
2. I noticed the 1TB SSUBX is wider than my original SSD. Since I don’t have my MBP at the moment, will the 1TB fit?
3. If I don’t buy a used Apple SSD, do you think I will be able be able to migrate to Big Sur with the 970Pro?
4. In your opinions, should I try and get Nvmefix and Lilu to work and will it port to Big Sur?
Thanks for all that all of you have contributed. I’m in your debt.
1. SSUBX will still pick up speed since even though yours is 2.0, it still x4. But again, UBX speed at most is 1200ish
2. 1TB should fit, i see the space is enough.
3. I think you will be able to use NVME drive in big sur.
And btw, you can do bootcamp in NVME drive, been doing it on dozens unit.
