No real difference.

What I've found in testing on different systems is the sim loves memory, memory bandwidth and VRAM (with obviously as fast of a GPU as you can manage). An SSD helps with initial loading, but stutters / microstutters are reduced when you can max out on the other three. Also tailoring your settings so your CPU stays under max load will help too.

Not substantially.  In benchmarks for storage read and write for sure and there will be some benefits once the DirectX Direct Storage is implemented but not sure if it will be implemented into MSFS

It does help loading a lot, especially when you have a lot if extras loading. 

But in game its not noticeable. 

Thanks guys ! Looks like ill pass on it. 

I have a m.2 but still have micro stutters. I think turning off ai and multiplayer traffic will have a bigger effect in solving them.

For me they are off since day one 🙂 along with all the other traffic options.

Two points to make:

 

1. Some M2 drives are SATA, these will perform identical to any other SATA drive.  The only advantage of M2 SATA over a normal 2.5" SATA drive is physical size.

2. NVME M2 drives can transfer several times faster than a SATA however you will only going to see a different during sustained reads and writes, in other words loading Windows, or sustained heavy database activity or possibly video editing. The difference between SATA and NVME in something like MSFS might show up in a shorter loading time (though even that is unlikely as the limiting factor seems to be the GPU and CPU decompressing textures)  but I doubt it will make much difference, if any, in flight.

With my March 2020 build I installed two NVme M2 2TB drives and they're fabulous.  Boot time is a few seconds.  As others have stated MSFS runtime likely won't be impacted much.   I bought two so could clone one to an identical other, which I've done mainly for P3D and the better part of at least one day required to install all of it and myriad scenery addons, aircraft, setup and configure.

I turned off AI traffic and got a huge performance increase.

Does this include Live traffic or strictly AI?

On paper a modern NVMe drive will blow a conventional SSD away in read / write performance but in reality the difference is not really noticeable. It might look good in a benchmark but it won’t improve your sim experience, other than perhaps cutting 1 second off your load times. That’s my personal experience swapping my Windows drive from a Evo850 to a Western Digital Black NVMe. The great thing about NVMe is no cables, keeps your system clean and airflow good.

Going from SSD to NVMe is nothing remotely like going from HDD to SSD. No one should be running their Windows or sim on an HDD anymore. For the cost, no other performance upgrade can come close.

I am rather impressed that my oldish I7-4770K@4,5 with 32GB RAM , GTX1080TI ,SSD Samsung EVO 2,5" 860 still manage to put out 29fps

You'd be FAR better off installing your OS on a new NVMe drive. Let the whole system actually take advantage of it.
