Upgrading 2013-2015 Macbook Pro SSD to M.2 NVMe

[bweliky]

I'm having issues on some of my systems -- I can't seem to figure it out

One system boots to the Apple logo in 10-15 seconds the other takes 30 seconds.

I've reinstalled High Sierra on the Intel Drive
I've reinstalled High Sierra on the original Apple SSD

Does anyone know how I can fix this please?

I have just received a Sabrent EC-NVME USB 3.1 enclosure which I have popped a spare 970 EVO into.

** SAMSUNG MAGICIAN WILL NOT ALLOW A FIRMWARE UPDATE IN THIS ENCLOSURE **

If your going down the EVO plus route, it may be more prudent to make sure you have a desktop / laptop running windows so you can upgrade the firmware if required, rather than rely on an external enclosure.

Actually Samsung ships the ISO to update firmware with. So You use tools like Etcher or rufus (on windows) to burn it on the flash and just boot from it so technically you won't need the seperate machine.

Hello, is there a difference if I buy a "pc"nvme disk or Transcend jetdrive 850 nvme in battery use and in hibernation ? Because I want to buy a bigger ssd for macbook pro 13 early 2015

Transcend jetdrive 850 nvme is more optimized for mac's than normal ssd nvme?

(Update on my recently bought 2015 MBP 15" i7 2.8GHz with the SX8200 Pro 2TB)

So I finally installed my SX8200 Pro 2TB. It was rather difficult to insert into the new Sintech adapter, felt like I was gonna break the SSD.. had to hold it by the sides and insert it at the same time as I pushed it from the back (no homo). With patience it finally popped in. I installed it with battery disconnected then slapped on the adhesive heat sink it came with, did a SMC reset & PRAM reset. I am getting pretty good results. Idles at about 0.18A, speeds around 2500MB/s Write, 2200 MB/s Read. Has Trim enabled (default). I partitioned it for macOS (800GB), Windows 10 (300GB) and an extra exFAT partition (900GB). Its easier to use a cheap 1TB SSD for the TimeMachine backup and useful to have extra SSD space for both macOS & Windows 10 to work with.

The fans blasted on the first couple startups with higher temperatures but that eventually stopped or happened less and the performance started evening out. I felt a bit concerned still so I decided to do something extra after reading more about the 2015 MBP's. Apparently the thermal paste wears out after 1-3 years under the CPU/GPU heatsink. I am able to confirm my stock 2015 MBP had very little. I attempted to use Thermal Grizzly Kryonaut and kept getting mixed results. Good temperatures at first, then hotter than usual under a stress test. So out of concern I shut it down and reattempted the application. Too much, too little, not even. I re-did it so many times and my results just felt unsatisfactory.. 90+ deg C when playing a game with Citra with fans at full speed with the GPU getting pretty hot as well.

So I decided to get the Thermal Grizzly Carbonaut. Carbonaut is a carbon pad that never needs to be replaced, is reusable and delivers perfect contact performance with decent conductivity. The IC Graphite pad doesn't perform as well as the Carbonaut when the Carbonaut is under a decent amount of compression. I got it on Amazon and decided to cut it from a larger sheet to save money and correct the size. I roughly measured the CPU and GPU die with a ruler, drew lines on a white paper business card marking the dimensions. Then I laid the pad on the card and used a good pair of scissors to precisely cut it while the corner of my thumb held it steady. After doing another SMC reset, PRAM reset and then putting it all back together, I am getting idle temperatures around 30-40 deg C with it dropping into the 30s more often than before. When playing Majora's Mask on Citra, I am now getting 58-75C with it keeping in the 60s more often than before as well (fans on).

Fans also completely stopped throttling after startup which I thought at first was because of the SSD. I didn't have many trials though with the SSD and old thermal paste before I replaced it. Overall, the laptop physically feels cooler than I previously remembered, especially when browsing the internet.

Anyways, these are just my results of setting up my 2015 15" MBP. I highly recommend the SX8200 Pro 2TB with the newer Sintech Adapter. No sleep issues at all for me. I also changed the sleep-hibernation delay and made a script to auto turn off wifi & bluetooth when closing the laptop & restart it when opening. Getting around 7 - 7 hours 30 mins battery life (88% health) usage with minimal battery dissipation when closed and put in my bag.

I also highly recommend the Thermal Grizzly Carbonaut to anyone with a MBP because thermal paste always need to be changed or else the CPU/GPU performance will decay over time. And please don't use liquid metal on your MBP. It will degrade the heat sink, CPU/GPU die, and will possibly need replacement by the end of the year.

I have 500GB not the 1TB version.Overall i'm satisfied with it.

A bit disappointed with a battery life, but im okay trading it for extra 400GB over stock 128GB SSD, More important for me that i have no longer have to choose between downloading several movies/storing large virtual machine image/having all folders from dropbox synced locally.

How are CPU temperatures for you? I installed a Kingston A2000 1TB with the short Sintech adapter in my MBPR 13" early 2015 2.9GHz 16GB RAM. Happy with the extra storage, and with hibernate mode 25 and short sleepdelays on battery, battery life is very good. BUT, even with new thermal paste my CPU idles around 49 C (compared to 34 with Apple SSD), with medium tasks around 70-85 C and sometimes on boot and intensive tasks peaks to 103 C (compared to max 85 C with Apple SSD). Measured and controlled with Macs Fan Control. This will damage my Macbook if this happens often.. and certainly reduce motherboard lifetime..

Unfortunately it didn't correct it

I've tried different SSD and adapters as well

Has anyone heard of this problem ever?

 

[neightdog]

i've used this sintech black short adapter with no issues, my setup below.

13" early 2015 MBP
1TB Sabrent Rocket

How has this set up been for speed? Any crashing with sleep/hibernation?

Try using Carbonaut and do a SMC and PRAM reset.. I had the same issue with thermal paste. you kind of have to angle the heat sink when you put it down. I think this makes the thermal paste spread somewhat unevenly. Also, when removing the heat sink, I kept noticing that most of the thermal paste got pressed out the sides of the CPU/GPU die leaving an inconsistent layer in between (probably because of the pressure). I am liking the Carbonaut myself. A high-end thermal paste might still provide slightly better performance, but it is inconsistent and only works as a short-term solution. With Carbonaut, the performance is pretty much within the temperatures I desire and is built to last for many years to come. Just be sure to cut it to fit the die. Leaving too much around the edges or on spaces surrounding the dies won't give you the ideal performance. I thought I could use one large sheet to cover the CPU area, but after I cut it into an L like shape it performed better. You also gotta make sure you don't move around the pad when you put the heat sink back on it, but as long as you're careful it should remain where you set it. Wish I took more pics, but at this point I really don't wanna take my heat sink back off again.

Hey, I have a 2014 15 inch MBP I just purchased used. It didn't come with an SSD installed so I put in a sx8200 pro(with a black sintech adpter) and installed catalina and it worked for about 5 hours until it kernel panicked and shut down. Upon restart I had the flashing question mark folder. I am now using it with a sata hard drive in a usb enclosure. The nvme drive doesn't appear in system profiler even after reseating it multiple times. Current bootrom is MBP112.0145.B00. I have a used apple ahci drive on the way but are there any tricks you know of that I can try to get this working?

Thank you for the suggestions. No improvements with SMC and NVRAM reset. I also let Macs Fan Control handle the (single) fan in my MBPR13" early 2015 for a steeper fan curve for lower CPU temperatures. I think your MBPR15" mid 2015 can handle the increased NVME speeds better because it is a quad core and mine is only a dual core. I used Arctic Silver 5 as thermal paste and should be fine. Used it successfully many times before. I chose Kingston A2000 1TB because the SSD itself would run cooler and would be more energy efficient compared to others.

Did anybody else have better result for CPU temperatures in a MBPR13" with other NVME SSD's like the XPG SX8200 Pro or Sabrent Rocket (TLC)?

 

[kombinat]

Hi guys,

I upgraded MBP 2014 with SM951 512GB. It went fine and I get ~1400 MB/s write/read speeds... until I put it to sleep even for a second - after that write speed drops to 60 MB/s, read remains fine at ~1400.

"sudo pmset -a hibernatemode 0 standby 0 autopoweroff 0" didn't help.

After restart write is back at ~1400... until it sleeps again.

Adapter I use is newest sintech - small black one (pins have tape on them).

I have some questions:

1)Can you provide a link to the Carbonaut you purchased?

2)How much over the edge (in millimeters) of the CPU and GPU should the Carbonaut overhang?

3)I have both 2015 MacBookPro and 2015 MacBook Air with upgraded SSDs. Should MacBook Air also be treated with Carbonaut?

4)Are there any videos or instructions I can refer to on take apart to get to the CPU/GPU heatsink and replace thermal paste/Carbonaut?

Thanks

13" early 2015 MBP 3.1 Ghz i7 16GB - 2TB SX8200 Pro - per iStats seems to idle / web browse around .18A, youtube .19A, heavy read writes spike to around .44A, generally about 5-6 hours typical use, could probably stretch 6-8 with lower screen lighting

long story short, happy with the storage upgrade, willing to connect more to a charger as a trade off.

Thanks for the feedback. Are you using the new Sintech adapter? Any sleep or hibernation issues? I have the same model mac.

Early 2015 MacBook Pro 13" (PCI-E 2.0 X4 so obviously bottlenecks the SX8200 Pro hence the lower numbers than a PCI-E 3.0 MacBook)
Bootrom 188.0.0.0.0 - Catalina 10.15.2
------------------------------------------------------------------------------
2TB ADATA "SX8200PNP" SX8200 Pro - Revision: SS0411BB
0.18A Idle. - 0.897A Read. - 0.898A Write.
------------------------------------------------------------------------------
512GB Apple "SM0512G" - "MZ-JPV5120/0A6" - Revision: BXW5TA0Q
0.01A Idle. - 1.54A Read. - 1.62A Write.
------------------------------------------------------------------------------
Tested with Amorphous Disk Mark with a 32GB size sequential test.
So 18X more power consumption at idle compared to the Apple drive, less flat out under load but that is not something that I do personally.

My MBP shipped with a 128GB SSD, I purchased the 2TB ADATA as it seemed to be the best option, was super unhappy with losing 2+ hours of battery life (felt closer to 3) and sleep not triggering hibernate so excessive power consumption while in sleep mode most of the time (sometimes it wasn't too bad sure, most of the time it was bad), sure I could disable standby and just force hibernate as a workaround, doesn't bring back the battery life loss in every other situation.

I ended up buying a 512GB Apple drive, should have just done that from the beginning.

I ended up doing just that...

Why do you think the choice of SSD will impact the heat generated _inside_ the CPU?

I don't believe there is any connection.

my 3.1ghz i7 13" early 2015 16gb, with factory thermal paste, after ssd upgrade to an SX8200 Pro (no Apple SSD cpu temps were tested, no Sabrent Rocket cpu temps tested during the ordeal involving two of those):

cpu idle temps: 49C,
max cpu temps observed on iStats 24hr graph: 87C
max cpu temps observed during cpu intensive task (sensor menu reading): readings of 100-102C with a brief showing of 105C
max temps observed on iStatus graph of above activity (assume different polling frequency): 98C

Intel max temp specification for this cpu (Intel i7 5557U) before max turbo speed will throttle back is 105C

Seems to be operating within specifications.

Happy with the extra storage, and with hibernate mode 25 and short sleepdelays on battery, battery life is very good. BUT, even with new thermal paste my CPU idles around 49 C (compared to 34 with Apple SSD), with medium tasks around 70-85 C and sometimes on boot and intensive tasks peaks to 103 C (compared to max 85 C with Apple SSD). Measured and controlled with Macs Fan Control. This will damage my Macbook if this happens often.. and certainly reduce motherboard lifetime..

I haven't noticed any difference in temps after an upgrade. Maybe it's because spotlight is indexing a new drive? Right now with chrome and some other not CPU intensive programs running in background temps stays around 49-53°C. It's common to get such high CPU temps when running MacOs because Apple tries to keep fan noise as low as possible sacrificing performance, CPU will throttle at such high temps anyway so I doubt it will cause any 'permanent' damage.

I was using a corsair mp510 of 960gb for 2 weeks and the system crashing, closing the lid for long time was killing it, while the battery remained good while this time, it was getting dry very quickly while actually using the computer. I dont know what to do now.

Anyone has find a good drive with no issues? I am okay with the battery, but not any other issue.

 

[uguryesilyurt]

I replaced my 13" early 2015 macbook pro's ssd with Samsung 970 Evo Plus 500 GB. It drain battery about 3.5-4 hours.There is no other issues. Performance is great. 2 years ago, I used OWC Aura SSD, it had same battery issue and also it was very slow. Now I want to change my ssd again. I spent lots of money until today. I read most of posts here. But I can't decide anyway. As i understand there is no hibernate problem on early 2015 models for Sabrent Rocket ssd. Should I choose Sabrent Rocket 512GB? Is it final solution? I don't need very high speeds i need longer battery life.

If you want no issues at all you have to go for a used original Apple drive.

 

[mbiork]

I just upgraded my MacBook Pro (Retina,15-inch, Mid 2015) 256GB original storage to an 1TB ADATA SX8200 Pro M.2 Gen3x4.

FYI, I am still running macOS High Sierra

Here are the hardware I bought / used :

JimiCable adapter (11 €)
JimiCable 12+16pin 2014 2015 Macbook to M.2 NGFF M-Key AHCI SSD Convert Card for A1493 A1502 A1465 A1466

ADATA XPG SX8200 Pro NVMe SSD (168 €)
ADATA Xpg SX8200 Pro Series NVMe SSD, PCIe 3.0 M.2 Typ 2280-1

Plugging the SSD in the adapter was easy, but plugging the whole thing in the Macbook connector was another thing. It went in easy on the first 2/3, but the last 1/3, I had to push quite hard to force it in and I was a bit worried about breaking it. However, it went well, it just that you need to push more compared to the original SSD that swipe in quite easy.

Here are the ADATA drive informations:

The Write & Read performance are stunning compared to the original one. The original SSD test show about 506 MB/s Write & 1835 MB/s Read, while the new ADATA SX8200 Pro show 2529 MB/s Write & 2912 MB/s Read


This is the Disk Speed Test of the Original Apple SSD (actually it's a Samsung)

This is the Disk Speed Test of the ADATA SX8200 Pro

No doubt, this is a huge improvement, I love it !

There may however be a small (or big, depends on your usage / needs) downside and that's battery consumption... I am not sure yet how much this is going to impact the battery draining, but here a some facts:

Here is the idle consumption of the Original Apple SSD (Samsung branded in my case)

Here is the idle consumption of the ADATA SX8200 Pro

So the original SSD idles at about 0.04A while the ADATA SX8200 Pro idles at 0.25A
This is a huge difference and I don't know yet how much this is going to impact on the battery draining / battery overall time usage. I need to run more tests but this could give you an idea:

This is almost in idles condition, screen on, no screen saver, Wifi is on, Google Chrome running, and I almost only write this feedback, made a few screenshot & a bit of Photoshop.

In my case, the battery usage is not really a big deal / issue because I mainly use my station at work / home, mostly plugged, and I have another Macbook Pro (Retina 13 inch mid-2015) that I use when I am travelling because of the size, and the battery autonomy that is much better.

The SSD heating if you check the stats I provided are the same, 38°C. (FYI I added on the ADATA SSD the heat sink it came with. I tried without, and it look like it's better with it, I think I was around 42°C without)

Sleep function is working the same as before, I didn't see any issue here, and I can't see any other difference so far.

Finally, I want to thank all of you for sharing your informations, feedbacks, I ended up doing this upgrade and made my own choices based on the reading of this thread, watching a few videos, and reading a few blogs.

Cheers,
Marc

Will pay

So I just installed the Sabrent 1TB SSD into my 2015 MacBook Pro 15" and so far it works well. Everything transferred over with no issues so far. But read/write speeds seem to vary. See results below. These are all with the new drive. Sabrent claims that this drive will get up to 3400/3000 read/write. Is there something I am missing? Also how do I enable TRIM? Is it enabled automatically? I'm on High Sierra.
