I am so confused. My main problem is still wake from deep sleep. The only I solved this was to lock the sleepimage file so that is is not writeable. No matter what I do this file gets created to when I lock it it works.
Hi,
I see you had lots of issue which could have been avoid if you had from the begining followed the recommandations of puting insulation tape at the back of the adapter and setting standby mode to 0...
Some problems already have been treated, you may read post post
#122 which presents a table of compatibility, post
#508 which tries to resume things as of today.
On your MacBook air 6,1 the BootRom doesn't allow the Mac to read the sleepimage from a NVMe drive at wake from standby mode.
So you have to disable hibernation : your standbymode has to be set to 0. Just type the following command :
sudo pmset -g standby 0
This setting stays even after a SMC reset.
Samsung EVO is overkill for your machine. If you tape correctly the top of the Sintech adapter you will get 4-Lane and almost 700 MB/s write, 1200 MB/s read. You will not get more from an expensive Samsung EVO. For a 2015 MBP I would invest in the EVO.
Samsung SSD may be overkill, the biggest problem is they still present issues : kernel panics on huge file transfers.
Every single NVMe SSD drive which have been tested here all work (except SM981 maybe a firmware too young...)
All NVMe drives offer decent speed and have 4x lanes (all 2013 and up Macs have PCIe 4x lanes connexion, except mac mini Late 2014 and iMac 14,4).
I think the need of SSD upgrade in Apple Laptop is not a problem of not having enough speed... it's more often having not enough capacity so those NVMe upgrades are a good thing in terms of price.
As for speed, you can see post
#295 with comparaison of speed of different models on a rMBP 2015
At the present, every of the following SSD can be recommended with a properly insulated Sintech adapter :
- Intel P600 (fast enough, cheap, only 512B so only 10.13)
- WD Black (fast enough, cheap, can be formated in 512B or 4K for Sierra compatibility)
- Toshiba XG3/XG4 (fast, affordable, can be formated in 512B or 4K for Sierra compatibility)
- Kingston KC1000 (fast, a little expensive, can be formated in 512B or 4K for Sierra compatibility)
As for the Samsung 960 Evo / Pro, I would still not recommend them until a macOS update make they work without repeated kernel panics
I think the deep sleep crash comes from either not being able to read from the deepsleep image or OS X not being able to write correctly to it. So for now the only option that works is to write-lock the deepsleep file. I have no better luck with hibernatemode 25 so I set it back to 0. Maybe this has to do with Intel 600p. Don't have a Samsung EVO at the moment but I had to solve it the same way with a Samsung SM961. I am waiting for an adapter so I can upgrade the 600p to see if it makes any difference.
This is not related to any brand /model of SSD here, this is related with reading the hibernation file on a NVMe drive.
No 2013-2014 mac is able to read the hibernation file from any NVMe SSD at wake up, even a genuine NVMe Apple drive. The same models of Mac with same Sintech adapter and AHCI SSD don't have this issue and can resume from standby (hibernation).

Update: MBA 201
MBA 2014: works with kapton tape on the sintech adapter (i'll post pic of my taped SSD now) but after a deep sleep it reboots. Now I try to disable the option to shut off the drive in the energy saving settings pane.
MBP 2013: I will try another time with kapton tape.
Where do you put the tape layers? Under the adapter? I also read in this thread that some people have added some sort of foam UNDER the adapter. Which type of material is that?
This one is the new version, with black PCB. I have more than 30pcs of that:
http://eshop.sintech.cn/ngff-m2-pcie-ssd-card-as-2013-2014-2015-macbook-ssd-p-1139.html
In the back of the PCB is written: M2 NGFF as 2013-207 macbook SSD.
Hi
monofase,
It's weird Sintech send you those new adapters. I'll order one to see if I have same problems as you.
In the mean time as you're in italy, I can send you from france a known to work sintech "v2" green adapter so that we can make cross tests.
The tape needs to insulate the pins on the back of the sintech adapter from the shield of the femelle MLB connector.
Also, have you check your BootRom versions ? reset the SMC ?
Again, the 960Evo is not at present the best choice, as of 10.13.2 there are still issues.
Hi,
I have been reading this thread for almost the whole day today with the hope I can find a solution to the problem I am experiencing, Samsung EVO 960 250GB SSD showing PCIe x2 (Link Width) instead of x4 in my mostly successful upgrade of Early 2015 13" MacBook Air. Apparently I found no one having the same problem. I know for fact that the Apple SSD I replaced had 4 lane storage interface. So it cannot be right this EVO 960 becomes 2 lane...

BTW I have the sintech adapter that most people on this thread use.
@gilles_polysoft, I appreciate all the helpful info you posted. But I seem to be an odd man with the low disk read/write speed. Any idea of what I did wrong or didn't do? I am still waiting for the Kapton tape for one.
I appreciate others' tip / suggestion as well. Happy New Year!
Hello
diginside
thanks for your greetings
The first thing you have to do is to put insulation tape at the back of the adapter, being it kapton tape or any insulation tape... having 2x lanes instead of 4x is a clear sign of a problem of insulation to my knowledge.
We have many users on this thread, having reported that insulation tape resolved the 2x lanes problem.
The key is to have a little thickness, so that the pins of the sintech adapter don't touch the shield and even stay far from it..
Also, I'm sorry but you have a 960 Evo which still has issues of kernel panics, reboots, as of today...
In top of that, your 960 Evo has a firmware revision 3 (revision 3B7QCXE7) which is knowns to have bugs...
Samsung hasn't yet published the expected "4B7QCXE7" firmware and you can't step back to 2B7QCXE7
