On 2015 Macs, 4K formatted NVMe drives are also trouble-free. 512B still have kernel panics on big transfers..
On 2013-2014 Macs, same thing plus you have to disable hibernation (pmset standby 0).
It only drains the battery more on long sleeps (more than 4hours).

How big do those transfers have to be? I'm constantly moving ripped mkv's and VM images of anywhere from 2 GB to 7 GB to a simple 3 TB USB 3.0 drive and haven't seen any KPs.

I think we can all agree by now that Sintech's adapters are the ones to get, they seem to have the least amount of issues.

Still can't get any SMART-related software to recognize my 960, though.

Huh, looks like I need to figure out how to install that nightly build, I've only got smartmontools 6.5 installed via homebrew.

It never occured for me with copy on regular platter hard drives.
It occurs on full backup with CCC on external USB 3.0 SSD : big transfer (>300GB) at high speed (>300MB/s).
I will investigate more...
At first I tought it was a temperature issue : macOS seems not to be able to read proprely temperature of NVMe SSD. I took some photos with a FlirOne of a NVMe SSD in standby and after a full zero write : it goes very fast to 75°C.

But what is strange is that the problem (KP on huge file copy) only occurs with 512B formatted SSDs (Samsung 960 Evo or Pro).
It doesn't occur with 4K formatted SSDs

I tried the following experiment to confirm the behavior difference by Format type, APFS or JHFS+.

Format external USB HDD with JHFS+ and install High Sierra (1013.1). Because it is HDD, it is not converted to APFS and remains JHFS+.
Format the internal NVMe SSD with JHFS+ and Restore (Disk Util.app) from the external USB HDD.
Start up from internal NVMe SSD and make user settings. The SSD boot disk of JHFS+'s High Sierra 10.13.1 is completed.

By specifying the no conversion option (--converttoapfs NO) of command activation, the target disk could not be specified and it failed.

JHFS + and APFS have different starting mechanisms. APFS refers to the Preboot partition inside the container.
Behavior of the internal SSD (NVMe) did not differ.

Sierra (10.12.xx) dose not support 3rd party(non Apple) NVMe SSD natively, so Kext patch(s) are need. Original Apple NVMe SSD (from MacBook Air 11-inch, Early 2015 AP0256H) may work.

Today a new adapter (large) of sintech arrived so I tried swapping it immediately. Surprisingly there is no problem at restart. I feel that contact has become good as the connector of the SSD has been replaced with a strong spring. The machining accuracy also improved and it fits in the same size as the genuine SSD.

On the other hand, a fatal error occasionally occurs in the NVMe controller at startup. (Attached file)

....this means the Sintech adapter improved but doesn't solve the problems with NVMe SSDs

Since it seems that the fatal error at startup is not a hardware problem from the estimation below, initialization of the entire SSD and a new installation are carried out again.

No error has occurred in the memory test. (Rember http://www.kelleycomputing.net/rember/)
It only occurs at startup.
It almost coincides with the time when introduced Windows using BootCamp. Windwos introducing is for SSD's SMART information acquisition. Adapter is irrelevant.
After that, the Windows partition was preserved while several new installations of High Sierra were done.
After installing High Sierra with JHFS+, it converted to APFS with Disk Util.app (it started from Recovery Disk and executed after Unmounted with Disk Util.app), it became in a state where it can not be set on the startup disk. Recovering of Disk Util.app had no effect. It seemed that some trouble was occurring.

The probability of occurrence of fatal error was about 20-30%, but it did not occur even after restarting 10 times after reinstallation. I will see a little more. I think High Sierra is still buggy.


After clean install and user setting, the trash box was not empty?? There was the file I threw away before clean install.
Even BootCamp partition deleted, there was ever "EFI boot" entry at startup manager, ob course nothing happened if selected.

Anyone know which NVMe SSD uses the least power?

Well, here's the power specs (average) for the 960 EVO models:

Typ. 5.3 Watts (250 GB)
Typ. 5.4 Watts (500 GB)
Typ. 5.7 Watts (1000 GB)

Peak power on the WD Black M.2 512 GB is supposed to be 8.25 Watts according to Storage Reviews, but that's not the average

Idle power is 5.5 mW on the WD Black, 40 mW on the 960 EVO.

WD Black has 160 TB write endurance, 960 EVO has 200 TB write endurance. Oddly, Samsung warranty is 3 years, WD warranty is 5 years.

WD Black probably has better error correction and trim function than Samsung but 160TB write endurance is a lot anyway....

In your opinion, would AHCI drive still be the best to purchase if need sleep and hibernation or NVMe stable enough with the new sintech adapter.

As for Apple NVMe SSD (SM2048L etc) , they are supported natively from 10.10.2 on all Mac from 2015
(and with BootRom update on late 2013-2014 macs)

There are still issues with 512B SSDs and High Sierra, as of 10.13.1 (and even 10.13.2 beta still does not yet resolve this).

I tested Windows 10 a long time with the same hardware (rMBP 13" late 2013 and Samsung 960 Evo), there is no issue under windows 10 so this is not a hardware related problem (sintech adapter is fine, SSDs also). It's more an issue with the IONVMeFamily kext of 10.13.0-10.13.1

Hopefully, there will be an update one day to the IONVMeFamily.kext (2.1.0) from 10.13.0 which is the culprit, to my mind.

I'll update the experience of my setup here:
WITH CableCC/Chenyang Adapter:
Overall Usability: Tolerable. Only have reboot issues.
Macbook Model: Macbook Pro Mid-2015(A1398)
Adapter: CableCC (Chenyang)
SSD Model: Samsung 960 Pro 512GB
BootRom Version: MBP114.0177.B00
BootCamp: Installed, with problem rebooting and error launching BootCamp Control Panel
Kernel Panics: Rare when taped(<2 times/month). Noticeable when untaped(1~2 times/day)

High Sierra cold boot time: >30s with APFS, ~10s using JHFS+(forced os installer to install using JHFS+)
Sleep issues: NO
Reboot issues: YES, showing nothing but black screen, have to force turn off and start.

Any hiberate policy modified?: NO(Factory Default)
P.S.
I'm trying to buy a Sintech Adapter, it seems CableCC is not the 'authentic' one? I'm in china, so it should not take long for the adapter to arrive.
---
Update:
I just received my Sintech Adapter(new version), and the reboot problem is gone!
WITH Sintech: Work like a charm!
Kernel Panics: Rare
Adapter version: New (bigger version)
Reboot Issue: No
Sleep Issue: No
Tape? : You still have to tape it.

Go sintech!
Yey!
:)

Would you be elaborate on your last comment "you still have to tape it."? What exactly does taping do and would you be able to confirm that you Mac can sleep but can also hibernate?

Also anyone noticed their NVMe SSD read performance is lower in Sierra than High Sierra is this normal or my drive is faulty?

Whats the large Sintech Called? Could somebody link it to me?
thanks in advance :)

Not 100% sure, but Sintech lists this part for $16, it seems to be a revision B of the previous part most of us have been using.

http://eshop.sintech.cn/ngff-m2-pcie-ssd-card-as-2013-2014-2015-macbook-ssd-p-1143.html

They have reduced the price of the older part most of us have been using to $8.99 US, and this new part is mysteriously $15.99 or twice the price of the old part. Hopefully that additional charge results in better quality.

I stuck in a Samsung Evo 960 into my MBP early 2015, and it works great, but often it fails to recognize startup disk, so I get the "flashing ?", so I turn it off and back on, and it boot fine. Is there a fix for this?
