Fusion Drive to 970 Evo Plus.

I have a 2014 Mac Mini (Core-i7, 16GB RAM, 1TB Fusion Drive). I would like to remove the current Fusion Drive (HDD + SSD) and replace it with the 970 Evo Plus (M.2) as the only drive. I don’t need to backup anything and would like to do a fresh MacOS install.

  1. Do I need to purchase anything besides the 970 Evo Plus (M.2) and related tools make this work?
  2. Are there any special steps I need to take before I install the new SSD?
  3. Do I install the 970 Evo Plus in the same slot as the original Apple SSD blade location?

M.2 SSD’s are not the same as Apples custom blade SSD’s So no you can’t use the blade connector for the Samsung EVO SSD.

Your system offers two connections the custom PCIe/NVMe blade interface as well as a SATA III (6.0 GB/s) interface. While the blade interface is the faster interface being custom does make things a bit harder. Here’s a good guide on the Apple SSD’s The Ultimate Guide to Apple’s Proprietary SSDs.

First before you do anything you do need to break the Fusion Drive set following this guide Split Your Fusion Drive Apart

I would hang onto the SATA drive as its still a useful drive if dedicated to a data only drive. I personally would get a 500 GB Apple SSD (SSPOLARIS) as my blade SSD. Making it my Bootable OS drive and hosting all my apps, and leaving the rest of the drive unused! That way the OS and my Apps have free space on the faster drive.

I don’t recommend M.2 SSD’s in Mac’s but if you are head strung on using them then you do need an adapter to convert the Apple connection to the M.2 connection. At least its easy to get to!

So why do you not recommend them? I’ve encountered more failures with them than with the custom Apple SSD’s. Either the drive or the adapter fails. What is hideous here is the adapter will kill the SSD.

Apple also uses some interface lines for other functions that are not replicated on the M.2 SSD’s so when you over fill the drive you’ll encounter a full breakdown unable to recover your files and sleep Mode won’t work correctly.

So while at the get go they look fine as the drive gets used it will buildup problems! I have a full drawer with dead M.2 drives and adapters I’ve pulled out of Mac systems.

Hi Dan, has anything changed about the situation since 2019?

I have a Mini Late 2014 with 2.25 TB Fusion Drive (2 TB HDD and 250 GB SSD).

What about the Samsung 970 Plus 2TB - now 3 years later? Does it work with the KALEA-INFORMATIQUE M.2 SSD adapter without any problems? Is it recognised as a boot drive? I would then just swap the 250 GB SSD for the 970 Plus SSD and use the HDD as a data drive, i.e. split up the Fusion Drive.

A hangover back in 1980 is no different today! I should know as I’ve had them and I still can’t find anything to fix that!

Sorry nothing has changed. To be clear I love M.2 SSD’s!! It’s Apple who had to do their own thing not following a common standard like SATA, Ethernet, video standards, DisplayPort, EISA mount for a short list.

The risk is your data if it’s not important the go for it!

I’ve had to many people crying when I tell them their presentation or video project, thesis or family photos are never to be seen again, using these adapters and M.2 SSD. And it makes no difference who’s.
