Hi

I'm preparing to do a new build based around the Gigabyte Z390 M Gaming micro ITX board. Am I right in thinking the M.2 NVMe SSD isn't worth the hassle?

You should be able to use a M.2 NVMe SSD if you install High Sierra or Mojave, which your motherboard paired with a suitable CPU should be able to run.

I got the impression from other posts that they have problems booting.

@orbec,

That used to be the case before MacOS supported non Apple NVMe SSD's, but High Sierra and Mojave now have native support for 3rd party OEM NVMe's so there are no patches or extra tricks required to make them work.

It's been like that for well over a year now.

As long as your BIOS supports booting from a NVMe drive you will have no issues, if your BIOS does not support booting from NVMe's then you can still install MacOS on to one and boot Clover from a EFI partition on a SATA drive which in turn will boot MacOS from a NVMe.

Cheers

Thank you for the explanation Jay. I think I'll give it a try.

And what about power management?
Is it true that there is not a proper power management for third party NVMEs on macos?
I want to buy one but I'm afraid of battery drain.

@DimitrisG,

Should not be an issue, i use a Samsung 1TB PM961 NVMe (PCIe x 4) which is the OEM version of the SM961 series of NVMe SSD's in my 2017 HP Spectre X360 and battery life is very good and the speed of the NVMe is pretty fast.

As long as you stick with a good quality NVMe (preferably Samsung) you should be fine.

Yes,

A good SATA-3 connected SSD's will top out around ~550MBs, A good NVMe will be at least 4-5 times faster at reads and at least 3 times faster at writes .... so Apps load and run faster, OS boots quicker ... etc

My NVMe is a few years old now ... current gen Samsung NVMe's can do over 2500 MBs writes and over 3000MBs reads.

Overall it just makes MacOS much snappier

Cheers
Jay
