Hi monofase,
Temperature is not linked in any way to the link width nor the protocol. Generally speaking Samsung drives run hot (my 2TB 960 Pro runs at 55°C idle and 73°C after huge transfers), but Kingston / Toshiba drives, even being fast NVMe drives with 4x PCIe 3.0 lanes, run at 39°C idle and 58°C after a long blackmagic test.

Very interesting. On Win10 1709, 2015 MBA 13 my 250GB 960 EVO runs extremely cool; it idles at 40C and rises up to 50C when I stress it with CrystalDiskMark 2GB. Could you please download CoconutBattery and tell us the power draw when doing various tasks with the Kingston/Toshiba drives (the figure below) and the MacBook model? I get 8-9W in HS 10.13.4 normally.

I successfully upgraded my 2015 15" rMBP with a large black Sintech adapter (ordered from Amazon US) and a Toshiba XG4!
I am currently doing a battery life test as well as compared to the stock SSD and I will post that as well later.

I eagerly await uintmax's battery life test with the XG4. I have seen tutorials on YouTube where people claim that there is no noticeable battery life drain with SM951 and rMBP because as stated above in this thread it's most similar to Apple's native UBX SSDs. 960 EVOs and 600p s are known to have higher than usual power draw based on experiences in this thread (I remember Audit13 mentioning this earlier.) If it really turned out to be the case that some SSDs have lower draw than others we should create a guide for people who need the extra battery life.

I would try and borrow a drive to perform the firmware upgrade.

It is a long shot but maybe the apple store can help?

Nope, they would only replace the SSD (and I don't know anybody willing to let me play with his SSD).

Would I still need the latest BootROM, should I give up with MacOS and go for Linux?

I understand your frustration. I'm not sure where you are located but it may be worth it to buy a used 128 GB Apple ssd to perform the firmware upgrade.

Yes, you could go with Linux but I think you would be missing out on a lot of features of macOS.

I bought a damaged Macbook Air just to have a spare 128 GB Apple Samsung SSD.

I don't have a lot of data just yet but so far I did a fresh install of High Sierra 10.13.4 on the XG4 and only installed amphetamine (to keep the screen on) and google chrome. The laptop is at 50% brightness and refreshing reddit.com/r/all every 15 seconds for two hours. In two hours the battery went from fully charged at 100% (8312 mAh) to 75% (5936 mAh).

I let the laptop sleep overnight for 8 hours and this morning when I woke up it is at 74% (5873 mAh). I'll try and test the stock Samsung SSD when I get home tonight.

You may consider two other models of 2 TB drives that are coming to the market lately :
- the Toshiba XG5-P 2TB (KXG50PNV2T04A) which can be found at around $800
- the Samsung 970 Evo which was just announced and should cost $850

Thanks Gilles. I have see the Intel 760p Series - 2TB: could this also be a good choice?
Merci

I purchased a THNSN5512GPUK NVMe TOSHIBA 512GB that was pulled from a Dell laptop off Ebay for $140. Installed in tandem with green sintech adapter ordered direct from their website.

I have Macbook Pro Mid 2015. System would not recognize the drive. Booted system with Debian USB, and Debian could see it. Formatted to EXT4, as I was unsure of what options if any would jumpstart iOS into seeing this thing? Reboot, nothing. I made sure the new disk had current Toshiba firmware on Win 10 PC.

Hooked up an external drive, using carbon copy I cloned my stock SSD to it. Made that the boot disk, removed stock and swapped in the Toshiba. I then booted, and the system showed it in disk utility. Formatted it there for APFS etc. I then used carbon copy to migrate from the external drive on to it. Made it the default boot, and everything works great.

What could I of done to make the system recognize it without the headache of that workaround? Is there any way to get APFS options with Debian or any flavor of linux?

Also this drive is fine for someone trying to be cheap like me, but its a tad slower than the stock SSD.

@dmeye25, was your Macbook running High Sierra off the original SSD before installing the Toshiba?

Were you booting off a High Sierra USB installer after installing the Toshiba?


Yes, my Mac was running high Sierra with all recent updates.

No, I was booting with just the drive. And doing the internet install. Is that the kicker? (Usb) I assumed if it doesn’t see it, then I was dead in the water. And did my described workaround.

I had a 2015 13" Air running High Sierra with an original 128 GB Apple SSD. I removed the Apple SSD, installed the large, green Sintech, 256 GB Intel 600p, kapton tape, and booted from a High Sierra USB installer. Disk utility saw the Intel with no problem. I created a single partition, erased the drive, and installed High Sierra without having to use Linux.

I’m not sure why my machine didn’t see it, I recall another person in this thread using one of these Dell/Toshibas and having the same issue

Just updated my 2014 MBP to 10.13.5 latest beta (4) and the bootrom has also updated to 146.B00 but sadly no changes to the NVMe state, still external on boot and internal when running.

Hey gang!
just ordered a 1TB PM981 to test with my Mid2014 MBP. I will also get my hands on a Mid2015 MBP for tests with both the PM981 and PM961.

I'm very interested in this test with the Samsung PM981 and I'm also very interested in anyone's experiences with the Evo 970 / Pro NOT the 960 since this is the newest technology. I'm assuming the 970 works just as well as the 960 since it's already compatible maybe even less heating / bottleneck issues since it's a newer build? Just waiting for confirmation from someone here...

Anyways, I feel we should start moving this thread discussion to the NEWER solutions since we already know the 960 evo works fine.

Just received the black syntech. I've the 960 evo (500gb) still closed. Hope to have a straightforward way to the upgrade solution.

Don't buy the PM981 drive if you are planning to use in macbook. It is not compatible I have already tried 2 brand new PM981 drives, half way through OS install macbook always crashes and restarts. Tried 2 different PM981 drives, tried on all macbook 15" from 2013 and 2015 and also tried air and updating the ssd firmware does not help. Maybe the official Samsung 970 won't have this issue. Best drives to use for macbook right now are the samsung 960 no known issues with them.

Right on man... thank you for the info about the PM981 I was just waiting for someone to confirm that has done actual test themselves, which it sounds like you have.

I still feel we need to find someone who’s done a test on the 970 evo because I just bought the 960 and I would return it if I knew the newer version worked.

As you know, 2013-2014 MBP or MBA and 2015 MBP or MBA behave quite differently with NVMe SSD. I saw what the difference is due to. Comparing the hardware, chips and circuits on the logic board shows the difference clearly. Chips and circuits are quite different regardless of which models are taken. I purchased junk and compare logic boards and We can compare logic boards on iFixit and other sites. If the chips and circuits that make up are not so different, I expected that it would be easier to port EFI firmware etc, but the expectation collapsed.

Given this situation, I do not think that Apple will take a lot of time and cost to properly operate NVMe SSD with the old model 2013-2014 MBP or MBA. Originally it was difficult to support NVMe SSD with 2013 - 2014 MBP or MBA hardware, so it seems that Apple developed 2015 MBP or MBA.

I am sorry to break my or your hopes, but I do not expect NVMe SSD to work without trouble at 2013-2014 MBP or MBA.

I understand fully about the hardware differences, but Apple could infact if they so wished, remap the bootrom/EFI firmware so that NVMe ssd's are seen as internal and not external at boot time. The Roms are not interchangeable between the 2015 and 2013/14 because as you say there are differences in the architecture including haswell/broadwell processors. The 2013/14 systems are perfectly capable of using NVMe drives, I have one running in a 2014 and when running, the drives are internal and work fine. It is only the long boot time and sleep problems that are a problem and this is because of the EFI firmware seeing the drives as external at wake/boot time where they were internal at run/sleep time. NVMe is a recent addition to the 2015 also but they somehow got this one right.

Just a stupid question, is possible to use the MBP late 2013 SSD in an external case after the upgrade with the 960evo? If yes, how?! :)

The late 2013 and 2014 macbooks work fine for NVME. I have no issues with them and the only difference I see is that the 2013 and 2014 macbooks can only run on 5GT/s while the 2015 macbooks run it on full speed of 8GT/s. If you are having issues on late 2013 it's probably because you are not using the correct adapter. And depending on the ssd you use, there is like a small lag time of like 4 seconds when you turn on the macbook if you are using a toshiba ssd didn't notice on the samsung ssd.

Ofcause I use sintech large green adapter, so adapter issue is not there. NVMe SSD issue with 2013-2014 MBP or MBA are shown as external drive, so it takes lag time at startup (in my case it is about 10 sec). I don't allow that shown as a external drive and taking lag time.

I recognize ;
MacBook Air 11,13 2013, 2014, 2015 x4 5GT/s PCIe 2.0
MacBook pro 13 retina 2013, 2014, 2015 x4 5GT/s PCIe 2.0
MacBook pro 15 retina 2013, 2014 x4 5GT/s PCIe 2.0

Hello all, I just stumbled upon this thread, I have tried to read the last page or two but I thought it would be easier to ask. I have a late 2013 15' rMBP and I had just ordered the 970 Evo 2tb m.2 for my desktop, I was wondering if it would work with any adaptor with my mbp, or perhaps any of the newer M.2 Nvme drives. I don't mind buying the adaptor and trying the 2tb drive first just to see if it works, before I get a 1tb for macbook. I do have Mac OS Sierra on my pro. And i am happy to post results and try tinkering as required.
Thank you!

I recommend updating to High Sierra using the original Apple ssd before installing an name drive.

I also recommend getting the Sintech adapter (large green) and some kapton tape.

Thank you, I have updated to High Sierra. Is there any difference between this

https://www.amazon.com/Sintech-Adap...&qid=1526043676&sr=8-1&keywords=ST-NGFF2013-C

and the large green adapter,

https://www.ebay.com/itm/M2-M-Key-S...863013?hash=item33d50f0365&afsrc=1&rmvSB=true

Seems like some people prefer this vs the others. I did notice, it seems most people with the late 2013 15" MBPs till the 2015 models have issues when the laptop goes to deep sleep hibernation mode. Is there anyway we can increase that time to beyond 4 hours. Its one of my favorite features, and I will resume working on my laptop usually in a few hours, perhaps increase that to 24hours or something.
